What vehicles does the OTOTUN1 fit?

The OTOTUN1 will work in 2007-13 Toyota Tundra & 2008-13 Toyota Sequoia, with or without JBL audio (JBL systems require additional cost data adaptor)

I’ve heard of similar decks from other manufacturers – are they in the same class as the Advent?

We have reviewed every “factory look” deck on the market, and we’re extremely confident in stating that the Advent is far and away the class of the field. When we’ve compared features, technical support, firmware updating, warranty, return rate, and overall customer experience with this unit versus the others, we don’t hesitate for a second to recommend the Advent as THE BEST navigation option for 2007-13 Tundra/Sequoia. Check out the comparison chart that lists the features and benefits of all of the aftermarket “Factory Look” units: Advent vs. Rosen vs. Myron & Davis vs. Metra

What makes the OTOTUN1 different from other aftermarket units I could install in my vehicle?

In contrast to universal aftermarket navigation systems from Alpine/JVC/Kenwood/Pioneer etc., that require adaptors and mounting kits to function in these vehicles (see chart below), Advent engineers have programmed all the necessary code into the unit to allow it function in an almost identical fashion to the factory head unit, so there are no other adaptors, modules or kits required to install it in a base radio equipped Tundra or Sequoia. It truly is a “Plug and Play” installation, with no modifications required to the vehicle whatsoever. JBL equipped vehicles will require the use of a data adaptor to retain the JBL amplifier.

The aftermarket navigation units also require a plastic trim kit to be able to bolt in, with varying cosmetic results, and which very obviously look aftermarket when installed. The look of the OTOTUN1 is as close to the factory navi as is possible, considerably reducing the chance for theft, as the factory navigation systems are FAR less likely to be stolen than high-end aftermarket units.

I own a 2007-13 Tundra/Sequoia with a factory navi system – can I replace it with the OTOTUN1?

All factory navi-equipped Tundras and Sequoias have the JBL audio system, factory rear camera and factory XM satellite radio. The factory unit can be removed and replaced with the OTOTUN1, but additional cost adaptors and additional labor will be required to retain the factory JBL amplifier, XM radio and rear camera.

If I swap my factory navigation system for the OTOTUN1, is there a market for the old unit?

Yes. Factory Toyota navigation head units with a current map DVD and GPS antenna are VERY expensive and can easily be sold on EBay. This makes the swap to the OTOTUN1 a way to actually get a better unit and MAKE MONEY!

I’m considering a lease option on my new vehicle – can I remove the OTOTUN1 after my lease is over?

Yes, since the installation of the OTOTUN1 is plug and play, there are no permanent changes made to the vehicle at all. This would allow you to remove the OTOTUN1 when your lease expires and either move the unit to your next vehicle (if it’s a valid application), or sell it outright once it’s been removed. Some leases will residualize the purchase, allowing you to be credited for the navi when the lease is over, just as if the vehicle came with it from the factory.

Do I lose any factory functions with the OTOTUN1?

Not necessarily. The OTOTUN1 retains almost all factory functions for almost all applications. Some of the additional features that may currently be installed and working in your vehicle, (such as XM satellite radio and backup camera) may be extra cost options with the OTOTUN1.

What is the bootup time on the OTOTUN1?

This timing varies depending on a number of factors. If you are entering the vehicle after the unit has been off for a period of time, we’ve measured bootup times between 12 and 18 seconds. If you turn off the vehicle and start it right up again, bootup is almost instantaneous.

I have the base radio in my truck – can I replace it with the OTOTUN1?

Yes. The OTOTUN1 comes set up to plug and play into the base Toyota audio system.

I have the JBL audio system – do I need any special adaptors to make the OTOTUN1 work in my vehicle?

Yes. The OTOTUN1 requires a JBL amplifier adaptor to function with the factory amplifier. This is an extra-cost option.

Do I need any other additional cost adaptors or cables to install the OTOTUN1?

All cables and adaptors are included with the OTOTUN1 to allow installation in the base (non-JBL) system: power/speaker harnesses, rear entertainment harness, GPS antenna and MediaLink cable. As noted above, the JBL audio system requires an amplifier adaptor to function.

My vehicle came with the factory camera display in the mirror – can I use it with the OTOTUN1?

Yes. The OTOTUN1 has a backup camera input included that will accept any standard backup camera, including the factory camera that displays in the rear view mirror (if equipped). Additional cabling and labor is required to incorporate the factory camera into the OTOTUN1. We have schematic information and installation photos available on our website that show the additional steps required to incorporate the factory camera into the OTOTUN1.

Will the factory camera display in the mirror still function when the camera is wired to the OTOTUN1?

Yes. The cabling required to route the camera to the OTOTUN1 does not interfere with the factory display, thus allowing both the mirror and the OTOTUN1 to display the factory camera’s picture.

I have a Tundra – is there a factory style tailgate camera available?

Currently, we are working with a supplier to develop a kit that will replace the factory tailgate handle with an exact match for the factory camera housing, only with a much better than factory camera. This kit should be available Q3 2012.

I own a Sequoia – can I add a camera to my vehicle?

Yes. We carry a “sugar cube” style camera that mounts in the factory location on the liftgate of the Sequoia, and comes with a much better sensor than factory that gives much better night vision and a much clearer picture than the factory camera.

Can I watch my camera while driving?

No. The camera input is active only while the vehicle is in reverse. However, ADC Mobile has developed a method that will allow this functionality with additional adaptors.

If I start my vehicle and put it in reverse, is there any delay on the backup camera?

You will normally see the backup camera display 7-10 seconds after a “cold start” when the vehicle is put into reverse. If you have tied the OTOTUN1 into the factory camera’s output that is displayed in the mirror, the delay on the OTOTUN1 will not affect the display on the mirror.

Can I add a “splash screen” to customize the unit to my vehicle?

Yes. ADC Mobile has over 375 custom splash screens that allow each unit to be customized to the vehicle in which it’s installed.

Can I make and install my own splash screens?

No. The splash screen is a proprietary format that requires special software to generate. This software is not available to the public, but we can convert customer graphics or photos for use as a splash screen (this service is available for ADC Mobile customers only). Contact us for more information.

Can I update the firmware in the OTOTUN1 and is there a cost to do so?

Firmware updates are always free and are done online via the Micro SD card contained in the reader under the “MAP” door. Visit and choose “Software Downloads” for the latest firmware updates.

Does installing the OTOTUN1 improve the sound quality of the base non-amplified audio system?

Absolutely! The OTOTUN1 has 45 watts per channel (45W x 4), which is more output than the factory head unit. Combined with a 9 Band EQ and loudness control, installing the OTOTUN1 will definitely give an improvement you can hear.

Does installing the OTOTUN1 improve the sound quality of the factory JBL audio system?

In our experience, the OTOTUN1 has far more control than the factory radio, and so gives you the ability to more finely tune the sound system, but the improvement in sound quality is not as dramatic as in the base, or non-amplified system. However, when combined with the 9 band EQ and loudness control, installing the OTOTUN1 will definitely give an improvement you can hear.

Is it a good idea to upgrade my base radio speaker system when I install the OTOTUN1?

In our opinion, the speaker system in the base truck is not great, but not extremely terrible either. By installing the OTOTUN1, you will see a big improvement in sound quality, so we recommend driving the vehicle for a couple weeks to determine what, if anything you feel you would need to upgrade in the factory speaker system. What we generally see when we swap out the factory speakers is that the system takes a HUGE hit in bass response, which means that unless you add some sort of subwoofer in the process, it’s not a great idea to swap out the factory speakers only. We suggest speaker upgrades in this order:

  • Subwoofer (either self-powered or with an additional amplifier, with input from the subwoofer output of the OTOTUN1) – the biggest bang for the buck there is in car audio!
  • Additional tweeters or replacement front speakers (2-Way, 3-Way or component speakers with crossovers)
  • Rear speakers (generally should be the last thing you spend money on)

What improvements can I make to my factory JBL audio system?

Unless you’re going to strip the entire JBL audio system from the vehicle ( amplifier and all speakers), there’s not much you can do to improve the audio quality of the JBL system. The JBL system has speakers that are incompatible with most, if not all aftermarket replacements, so there’s not much out there to even attempt an upgrade with. There are some aftermarket sound processors that claim to improve the quality of the factory system, but we have yet to try them.

Can I use the included Micro SD card to store music or movies?

No. The Micro SD card is for navigation data storage only.

Does the OTOTUN1 have an HD Radio tuner built in?

No. It contains a standard AM/FM tuner only and is not upgradeable to HD Radio.

Does the OTOTUN1 support the RDS (Radio Data System) display technology?

Yes. Just like the factory Toyota radio, the OTOTUN1 has an RDS tuner which will allow full data display of song/artist/station data if the radio station you’re listening to transmits it.

My vehicle came with factory XM – does the OTOTUN1 retain it?

No. When the factory radio is removed from the vehicle, XM satellite radio will no longer work. To retain it, you must purchase the CNP-2000UC tuner and CNP-JEN1 cable. We sell an additional cost antenna adaptor that allows you to retain the factory XM antenna, eliminating the need to mount an external XM antenna.

My vehicle did not come with factory XM – can I add it?

Yes. The OTOTUN1 allows the addition of an aftermarket XM satellite radio tuner. There is no Sirius option.

Can I add Sirius instead of and XM satellite tuner?

No. The OTOTUN1 only supports XM.

How does replacing the factory radio affect my XM subscription?

If you have a current subscription on your factory XM tuner, you will be able to transfer it to the new XM tuner by contacting SiriusXM. You can find the Radio ID on the new tuner at channel 0.

What radio presets are available on the OTOTUN1?

The OTOTUN1 supports 6 AM, 12 FM and 18 XM presets, only accessible while in each source.

What kind of audio controls are available on the OTOTUN1?

It has a full 9 band equalizer with three built-in and three user presets, as well as a loudness control and full front-rear and left-right fader and balance controls. If used with an outboard amplifiers for an optional subwoofer, there are subwoofer controls for crossover and output level.

My vehicle doesn’t have the factory rear entertainment – can I add rear entertainment to the OTOTUN1?

Yes, the OTOTUN1 has standard Red, White & Yellow female RCA outputs for connection to any aftermarket rear entertainment overhead or headrest monitor(s).

I have the factory rear entertainment screen – does the OTOTUN1 retain it?

No. In fact, since the factory rear entertainment option is a stand-alone overhead screen with DVD and is very complex to combine with the OTOTUN1, we do not guarantee any operation of factory rear entertainment besides DVD playback on the headphones ONLY. We currently do not support any ability to wire the two together.

Can I add other sources to my rear entertainment system?

Yes, through the use of an outboard A/V switcher. You would set it up with the rear A/V output of the OTOTUN1 hooked to the “A” source input, the other source hooked up to the “B” input, with the output of the switcher hooked up to the input of the rear screen.

Can I play a different source on the OTOTUN1 while the rear seat passengers are watching a DVD?

Yes. With the “Rear LCD” Dual Zone controls, the rear seat passengers can watch a DVD while front seat passengers can enjoy any other source. Audio from the vehicle speakers will be the source that is being played up front, while DVD audio will be available on headphones for rear seat passengers.

My vehicle came with a factory USB/AUX input – can I still use it with the OTOTUN1?

The OTOTUN1 comes with a “MediaLink” USB/AUX jack that replaces the factory USB/AUX (or AUX only in older vehicles) plug in the factory location. This jack has a rubber flap that covers it, making it look completely stock.

What is a “JLINKUSB cable”?

If you use the USB cable provided with your iPod or iPhone, you will only be able to play audio – video will be unavailable. The JLINKUSB cable allows for audio and video playback from any recent iPod or iPhone device.

I have an Android phone – is there a cable that allows audio and video playback on the OTOTUN1?

No. Since Android is open source OS and is not a stable hardware/software platform, there is very little device-specific support for these phones from any manufacturer. The A2DP Bluetooth function will work with most Android devices, allowing audio playback, but there is no way to play back video from Android device without using multiple additional adaptors and connecting it to the “A/V In” source using a 3.5 mm to RCA adaptor.

I have an iPod/iPhone – is it compatible with the OTOTUN1?

The OTOTUN1 is fully “Apple-certified” and allows full album art, artist & song data, as well as full control of audio and video playback on all late model iPods and iPhones. Some prior versions of the iPod are not fully compatible with the OTOTUN1.

Can I play back video files from my iPod or iPhone?

Yes, when using the JLINKUSB cable, you can play back video from iPod or iPhone. It also allows you to play back streaming video sources such as Netflix, YouTube or Slingbox via the JLINKUSB cable as well.

I store music and movies on my USB stick – can I play these back via the MediaLink’s USB input?

The unit can play back MP3 audio files via a file browser type interface. It is not capable of playing back any video files via the USB input.

Is there any way to play digital video files on the OTOTUN1?

The only easy way of playing video files is to copy them to your iPod or iPhone in iTunes and play them back using the JLINKUSB cable. If you want to play back digital video files from a USB stick or hard drive, the easiest way we know of is to add a media hub device like the WDTV Live.

This media hub runs on 12 volts and allows a very easy connection to the OTOTUN1 that allows you to add multiple USB devices and display photos, play back audio and video and even play games. Watch the video we shot showing our own WDTV Live installation.

Is the OTOTUN1 capable of playing DVD’s if I don’t have a rear entertainment screen?

Yes, DVD playback on the OTOTUN1’s screen is possible when stopped. It supports 16:9 and 4:3 viewing modes. It comes factory set to play DVD Region 1 (North America) discs only. The ability to change DVD regions is accessed via a hidden “installer-only” menu.

I want to allow my passenger to watch DVD on the OTOTUN1 while driving – is this possible?

The unit monitors the parking brake lead and will only allow video playback on the screen when the emergency brake is engaged and this lead is grounded. There is a mode accessed via a hidden “installer-only” menu that will allow video playback while moving for test purposes only. DVD playback is always available on the rear entertainment screen.

How many CD or DVD discs is the OTOTUN1 capable of loading at once?

The CD/DVD drive is capable of accepting one disc at a time.

Can I play both CDs and data discs containing MP3 files?

Yes. The OTOTUN1 supports CD audio discs and displays the type of disc currently inserted, title number, track number, elapsed time, file, folder, and stop/play/pause status information. It also allows shuffle, repeat and direct access to audio files on CD discs.The unit plays MP3 songs in the order they were burned on to the disc. The unit will play a MP3 disc with up to 500 songs and/or 200 different folders. You can view and navigate between folders and files with the controls on-screen.

I want to add an amplifier and subwoofer to my system – can I do this with the OTOTUN1?

Yes, the OTOTUN1 comes with four channel RCA outputs for adding a standard four channel amplifier, as well as a mono subwoofer output with full subwoofer crossover and level controls accessible from the audio menu. Outputs are rated at 2 volts.

I have factory Bluetooth – does the OTOTUN1’s Bluetooth system replace it?

Yes. When the factory radio is removed, the factory Bluetooth system no longer functions. The Parrot Bluetooth system in the OTOTUN1 functions in place of the factory system.

Can I use my steering wheel control for the OTOTUN1’s Bluetooth hands-free system?

Yes. All factory Bluetooth steering wheel controls will work on the OTOTUN1 as they do on the factory system.

Can I use the factory Bluetooth microphone for the OTOTUN1’s Bluetooth hands-free system?

No. The Advent uses an external, wired Parrot microphone, and it is required for the use of the OTOTUN1’s Bluetooth hands-free system.

Does the Advent support voice dialing via Bluetooth?

The Advent system accesses the voice dialing capabilities of your phone, so as long as your phone supports voice dialing, that function will be available when using the Bluetooth system on the OTOTUN1.

How many Bluetooth devices can be paired to the OTOTUN1?

The OTOTUN1 can accept up to ten devices and any device can be chosen to connect to the OTOTUN1 at any time via the menu.

Can the OTOTUN1 download the contacts from my phone?

Yes. The OTOTUN1 can download up to 2000 contacts from any phone and allows alphabetical access to those contacts via the menu. NOTE: not all phones allow contact download via Bluetooth.

Are Sent/Received/Missed call logs available?

Yes, extensive Sent, Received and Missed call logs are available, with the latest call showing at the top of the list.

Does the OTOTUN1 support Bluetooth Audio Streaming (A2DP)?

Yes. You can stream music to the OTOTUN1 from any source via A2DP protocol, including music contained on the device or any streaming audio source available on the device.

Are there restrictions on which A2DP devices are compatible and what functions they will support?

Bluetooth provides an Advanced Audio Distribution Profile (A2DP) profile for streaming music from a wireless phone or a Portable Multimedia Player (PMP), sometimes referred to as a MP3 player. The unit allows you to play back audio files from your wireless phone or a PMP using a Bluetooth connection. The unit can control a Bluetooth audio player via Audio/Video Remote Control Profile (AVRCP). Bluetooth audio players (or Bluetooth adapters) compatible with these profiles can be connected to this unit. Functionality varies depending on the profile used.
•A2DP: Stream audio from your Bluetooth compatible audio player and listen to the music through the unit.
•AVRCP: Play back, pause, select songs, etc. while streaming audio from your Bluetooth compatible audio player to the unit.
NOTE: Song information (e.g. elapsed playing time, song title, song index, etc.) cannot be displayed on this unit. Since there are a number of Bluetooth audio players available on the market, operations with your Bluetooth audio player using this unit vary greatly. Please refer to the instruction manual that came with your Bluetooth audio player.

Can I play music via Bluetooth from my phone and from streaming sources like Pandora and iHeartRadio?

Since the OTOTUN1 has A2DP Bluetooth Audio Streaming capability, it will support any audio streaming source via Bluetooth. This includes the music contained on your phone or other Bluetooth device when paired. If you are using an Android device, iHeartRadio and Pandora playback will only be available via Bluetooth and will not allow any song data, album art or control – this will only be available on the phone.

If you are using an iPhone, you can stream iHeartRadio or Pandora via Bluetooth, but since the OTOTUN1 supports Pandora as a native source when using the JLINKUSB cable, you can have full control of your Pandora experience, including album art, song and artist data, access to channel lists, next track and thumbs up/down control just by plugging in the JLINKUSB cable and starting your Pandora app on the iPhone. Download the manual for Pandora operation.

The OTOTUN1 ships with iGo Primo navigation software, which in our opinion is the most capable, most customizable and most informative navigation software currently available from any manufacturer, OEM or aftermarket. iGo Primo allows more data to be displayed than any other system, in more ways, with more clarity and more options and has proven to be extremely reliable and informative . It has revolutionized the entire Advent family of navigation products. You can watch a very in-depth (30 minute)video that covers every aspect of the navigation system operation here.
The map updates are done online via the Micro SD card contained in the reader under the “MAP” door. Advent’s “Latest Map Guarantee” insures you’ll have the most current maps loaded in your unit – within 30 days of purchase, log in and download the “NaviExtras Toolbox” from and it will automatically update your map database if required. Subsequent updates will run $129 per year.
There are no built-in restrictions against using the navigation system while moving. However, entering addresses and other navigation operations requiring data entry should ONLY be done by a passenger or by the driver while stopped.
No. The iGo Primo system does not support any voice-activated functions.
Yes. There is an “Auto Switch to GPS” menu setting that will allow you to always view the Navigation display while driving. If you access any other menu function, this setting will automatically return the unit to the Navigation mode after an approximately 10 second delay.
The iGo Primo system supports 2D or 3D viewing modes, with direction of travel or “North Up” display.
Yes. The system can warn you when you approach red light & speed cameras, or dangerous areas like school zones or railroad crossings. ADC Mobile has a list of all Red Light cameras in the USA available, and you can add your own, as well as being able to determine the type of warning you want to receive when coming close to the Alert Point (audible, visual, etc)
Yes. You can set audible and/or visual warnings to warn you when speeding, as well as the threshold (as the percentage in excess of the speed limit) to warn you at.
Yes. The NaviExtras Toolbox allows you to add your own POI lists, as well as import other freely available POI lists available from thousands of websites.
Yes. Using a readily available freeware program, many of the options and interface items such as colors, fonts and text sizes, as well as the ability to override certain “required” inputs can be changed to suit your preferences.
Spoken commands are available in English, Spanish and French. Program languages are Dansk, Deutch, English (UK), English (US), Espanol, Espanol (MX), Francais (CA), Italiano, Nederlands, Norsk, Portugues, Portugues (BR).
FAST: Gives a quick route if you can travel at or near the speed limit on all roads. Usually the best selection for fast and normal cars.
SHORT: Gives a short route to minimize the distance to travel.
Usually practical for pedestrians, cyclists or slow vehicles. Searching for a short route regardless of the speed, this route type is rarely practical for normal vehicles.
GREEN: Gives a quick but fuel efficient route based on the fuel consumption data given in Green Routing settings. Travel cost and CO2 emission calculations are estimations only. They cannot take elevations, curves and traffic conditions into account.
EASY: Results in a route with fewer turns and no difficult maneuvers. With this option, you can make iGo Primo take, for example, the freeway instead of a series of smaller roads or streets.
No. Statistical traffic information is stored with the map data, and iGO primo can take that into account when planning a route. In normal cases, these statistics help you avoid usual traffic jams on the given day of week in the given hour, but in some cases like on public vacations that fall on normal weekdays, they can be misleading.
If you use an iPhone and have purchased the “Motion-X GPS Drive” app, you can output any of the map displays the app is capable of generating, including live traffic and photographic views of your maps. Watch the video that shows how to use this great app with the OGM1.
Yes. The data generated by the system allows you to view detailed information on per mile costs for any trip you take (provided you enter mileage and fuel cost data at every fill-up), and it is capable of providing reminders for regular maintenance when it is required (provided you enter the intervals you want to be reminded of).
Yes. It allows you to search for “Green” alternatives for any trip, using lower fuel costs and lower CO2 emissions as your priority when calculating the route.
Yes. When routed via highways and freeways, the system provides a “flyout” display on the map screen showing the availability of your pre-chosen POI’s that are easily accessible at the upcoming three exits on your route.
Yes. The iGo Primo system can generate and save your trip logs that provide a wealth of data, such as tracks of your trip that can overlaid on the map, time-speed-altitude graphs and other information that may then be converted with different tools allowing it to be utilized in Google Maps or in Google Earth.
