It does what it says it does period... If your not a professional installer use the help crutchfield provides

Pros: It works and easy to install

Cons: I feel like it should be $20.00

Well, it works, for the most part.

Crutchfield Customer Review (What's this?)

Well, it did seem to integrate my factory sounds like door chime and blinker, etc. This is very important and I'm glad those things work, but the door chime is VERY loud while the blinker can barely be heard. So, now I need to go tear things apart again and see what I can do to resolve these issues.

Pros: Integrates factory sounds into new sound system

Cons: Complicated wiring with challenging instructions. Bulky box too stuff behind the stereo during install. Loud door chime, quiet blinker.

False advertising!!! Not happy

Crutchfield Customer Review (What's this?)

The fact your website and product state I can connect to factory xm but couldn't! I am completely unhappy cause I had to get the xm tuner


Cons: You lie and say it can connect to factory xm radio and then it doesn't

Crutchfield response on January 20, 2015 We're sorry that the adapter didn't get the satellite radio working for you. According to the manufacturer, the AX-ADBOX2 should have worked with your vehicle to retain control of the factory satellite radio. The downside is that you'd have to use the steering wheel buttons to control the satellite radio and channel and song info will only show up on the factory Driver Info Display - not on your new stereo's display. That might've been part of the problem. We hope you've had a better experience with the external tuner we sent you - it'll let you control everything from the stereo.

Factory Amplified/Non-Amplified Compatible: The Axxess AX-ADBOX2 interface module can be used in vehicles with or without factory amplifiers, including digital amplified systems. The AX-ADBOX2 provides an amp turn-on lead (Blue/white) to turn on any factory amps. Retains balanced & fade in vehicles with factory analog amplifier. Does not retain fader in vehicles with factory digital amplifier.

Navigation Outputs:  The Axxess AX-ADBOX2 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-ADBOX2 is designed to retain this feature.

GM Onstar Retention + Other Retained Features: The AX-ADBOX2 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-ADBOX2 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-ADBOX2 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.
