Versatility and compatibility

This Axxess module works with amplified, non-amplified, or digitally amplified systems. The AX-ADBOX1 gives you a "plug and play" connection for the Axxess ASWC-1 steering wheel interface (sold separately). And if you're installing a new navigation receiver, the AX-ADBOX1 also includes the parking brake, reverse, mute, and Vehicle Speed Sensor (VSS) outputs you'll need. This Axxess adapter also retains the digital fade included in some factory amplified sound systems.

Installation note: The Axxess AX-ADBOX1 must be used with one of the following Axxess vehicle-specific interface harnesses: AX-ADCH01, AX-ADCH02, AX-ADFD01, AX-ADFD02, AX-ADGM01, AX-ADGM02, AX-ADGM03, AX-ADMZ01, AX-ADTY01, or AX-ADVW01.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if the AX-ADBOX1 and its accompanying harness are compatible with your vehicle.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Axxess AX-ADBOX1 Interface Module

Doug from Yorktown, Va on 3/24/2017

2012 Ram 1500
Crutchfield Customer Review (What's this?)

As of now the sound continues to fade from back to front while playing, still trouble shooting, may change rating if it begins to work correctly.



Crutchfield response on 3/27/2017 Doug, we're sorry you're having issues with your interface. If the problem continues, please reach out to our tech support team. They can either help get the interface working the way it should, or possibly return it for an exchange or refund.

Crutchfield Customer Review (What's this?)

Works as advertised. Some features didn't work on my vehicle but still a good product.

Pros: Pretty easy to install.

Cons: Not all features worked. Like the dimmer. The steering wheel buttons require a separate module. You have to buy a separate harness to make this module work.

2005 Toyota Sienna
Crutchfield Customer Review (What's this?)

I gave this 3 stars because not all the speakers work. I've double checked all the connections and still no joy. I will call Crutchfield and ask for a replacement.

Pros: Can't provide one

Cons: Not fully functional

Had to Return

JoeyD13 from new castle, PA on 1/22/2016

2010 Dodge Ram 1500
Crutchfield Customer Review (What's this?)

Everything worked fine initially, but I had to return the product after three weeks of use. My speakers started cutting in and out, and I believe it was due to a faulty interface. I would jiggle it around, and all kinds of bad things would happen. I even soldered all the connections, but it didnt make a difference. I'm rather disappointed.

Pros: Everything worked good for approximately three weeks.

Cons: After three weeks, some weird things started to happen such as my speakers cutting in and out.

Marc from Indiana on 12/19/2015

2008 GMC Acadia
Crutchfield Customer Review (What's this?)

Was not a fan....... Cut, rewired multiple times still could not get all the functions to property work for the GMC Acadia. Luckily Crutchfield had my back and supplied a back up plan that was the way to go!! Maestro! Way to many wires and other connections on the Axxess products.

Pros: The ability to maintain all your features.

Cons: Way to many wired connections.... Required two different boxes and a couple harnesses. Once all together there wasn't enough room to tuck it all away.

Easy to use

Rick_okla from Oklahoma on 6/6/2015

2008 Chevrolet Equinox
Crutchfield Customer Review (What's this?)

Easy to use and made my install fast and cheaper than the box store quoted me

Pros: Easy to read instructions



Tech89 from Columbus City, Iowa on 5/5/2015

2009 Buick Lucerne
Crutchfield Customer Review (What's this?)

Bought with the other interface to make it virtually a plug and play install. It was. Some heat shrink and a some solder got the job done. A bit time consuming. But worth it.

Pros: Ease of use

Cons: Vague instructions

Raymond from Montana on 3/25/2015

2007 GMC Yukon Denali
Crutchfield Customer Review (What's this?)

Great interface and worked like a charm after some tweaking and some truly exceptional assistance from Crutchfield customer support. Without this and the accompanying wires and harnesses, installation of my stereo would have been a nightmare. This worked great!

Pros: It worked great and the included wiring and harnesses made installation a breeze.

Cons: None that I can think of.

Pros: Simplicity

Cons: N/A

Better than the PAC

JohnC from Charlotte, NC on 11/2/2014

Crutchfield Customer Review (What's this?)

I got this Axxess based on the recommendation of my installer. He uses PAC units in his shop as well, however if you have a Toyota with JBL and want to continue to use it then go with this!

Pros: Works great and sounds great!

Cons: No cons

It took time and effort, but we got it working!

Dale of Colfax from Colfax, CA on 9/12/2014

2007 Toyota Sequoia
Crutchfield Customer Review (What's this?)

3 stars for "it should have worked in the beginning", 5 stars for the effort put in by the manufacturer's engineers to get it to work for my apparently difficult vehicle. It took 4 software downloads, three weeks, voltage measurements, and detailed descriptions of the failures but we got the interface box to work with the new Stereo head unit and the 2007 Toyota Sequoia JBL amplifiers and speakers. Otherwise I would have had to replace everything. I bet anyone buying a new unit with the 1.15 software upgrade will have no problem getting everything to work.

Pros: Saves me from getting new amplifiers and speakers for the Stereo upgrade.

Cons: It should have worked up front but I guess you can't test for every vehicle...though a Toyota Sequoia isn't really rare.

Instructions are hard to understand

Pros: Steering wheel controls

Cons: Instructions

No issues

Acme99 from Orange County, CA on 4/4/2014

2004 Lexus RX330
Crutchfield Customer Review (What's this?)

It's not a sexy purchase, but it is an important one. I bought all Axxess harnesses for my install. Glad I did. My installer was stoked because it's a common product and apparently it auto-detects the car. Maybe I'm wrong. But I'm the end user, the installer was happy, and it works.

Pros: It works perfectly


Worked perfectly

Mark C. from La Mirada, CA on 1/25/2014

2004 Toyota Tundra
Crutchfield Customer Review (What's this?)

I bought this adapter along with a DVD receiver to integrate and to retain the audio functions of my existing amplified factory sound system. Very easy to install with the clear instructions and worked perfectly in my installation.

Pros: Does an excellent job of integrating factory systems to an aftermarket head unit

Cons: none

Axxess AX-ADBOX1 for Ford Focus ST

fragout! from Germany on 11/21/2013

2013 Ford Focus
Crutchfield Customer Review (What's this?)

I installed this on a Ford Focus ST w/basic cd player and 6 speakers. Everything works great! I also received the harness that goes with this which is a must. When I took it out of the package, I was a little intimidated by all of the wires. But after reading the instructions multiple times, I realized I didn't need all of the wires. When installing this, I would recommend separating all of the wires you need from the ones you don't. Tape up all the extra wires and then attach the wires you need to your radio wire harness. it's easier if you do this at the kitchen table and not in the car. I also like the fact that the harness included a cable attachment that fit directly to the Axxess steering wheel control (Axxess ASWC-1) eliminating the need for all the wires that came with the steering wheel control. You just need to plug it in. It also worked with my Sync system. This is great because now I can have an aftermarket radio and can keep Microsoft Sync. I'm happy with this product.

Pros: Easy install; No splicing of any of the car wires, everything connected to the car's harnesses, lets you keep Microsoft Sync

Cons: You need to closely follow the instructions.

Factory Amplified/Non-Amplified Compatible: The Axxess AX-ADBOX1 interface module can be used in vehicles with or without factory amplifiers, including digital amplified systems. The AX-ADBOX1 provides an amp turn-on lead (Blue/white) to turn on any factory amps. Retains balance & fade control in vehicles with factory analog amplifier or factory digital amplifier (non-THX systems only).

Navigation Outputs:  The Axxess AX-ADBOX1 auto-detect system interface provides a VSS (vehicle speed sense), Parking Brake, Mute, and a Reverse Gear output to make installing an aftermarket navigation radio simpler and less time consuming.

R.A.P (Retained Accessory Power): The ignition power source of many vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The AX-ADBOX1 is designed to retain this feature.

GM Onstar Retention + Other Retained Features: The AX-ADBOX1 is designed to retain the factory OnStar emergency services system that would normally be lost when your GM factory radio is replaced by an aftermarket head unit. This interface module will also retain your GM factory Bluetooth & Satellite Radio functionality. In addition, the Axxess auto-detect system interface retains your GM vehicle's factory warning chimes and turn-signals. It even allows you to keep your factory back up camera and rear seat entertainment.

Ford SYNC Retention: The Axxess AX-ADBOX1 retains all functions of the Ford SYNC system; including Voice Recognition Music Search, USB, iPod, Auxiliary Input, Bluetooth Phone & Audio Streaming, Turn-by-Turn Navigation, 911 Assist, and Vehicle Health Report.

Optional Steering Wheel Control Interface: The vehicle specific wiring harness (sold separately) features a right-angle 3.5mm connector that lets you keep your vehicle's OEM steering wheel controls via the optional Axxess Steering Wheel Control Interface (120ASWC1, sold separately).

16-Pin Harness Color Codes: The Axxess AX-ADBOX1 includes a 16-pin harness which connects between the interface module and your aftermarket receiver. These connections will need to be crimped or soldered together.

Hey it's for newer cars 2000 and newer it keeps your security alarm working and all the chimes when an icon pops up on your dash. It wires into the radio adapter [ Cody  Aug 08, 2015 ]
I had to use this on my Lexus. This item connects the aftermarket radio wires to the wires that the factory radio used. You must use it when installing a new radio. It basically powers the radio and translates the data from the new radio to the cars speakers. [ Patrick  Aug 07, 2015 ]
It plugs in line on your factory wiring harness, to your head unit. It works great with my pioneer head unit, however my only complaint is if you turn your volume down for a while it will cutout your volume all together until you turn it up again [ BRENT L  Aug 07, 2015 ]
