Heise Axxess Gm Data Interface 2000-2013

Well known brand that does exactly what it states.

Works good to keep factory chime and keep aftermarket stereo power on after key turned off.

Horrible. It doesn't fit a 2011 Tahoe, and the product says it will fit until 2013. Horrible.

This kit made it very easy to install a 3rd party Android head unit in my Grand Prix. One issue with doing this type of install is the warning signals, you know, the dinger that rings when the key is in the ignition when the door is open or when an idiot light comes on, plays through the factory radio and when removed that signal is no more. This harness includes a small speaker box that restores the signaling. The harness is easy to connect with the 3rd party head unit cable and then the whole thing connects up with the factory plugs so no hacking on the cars wiring. I'm glad I researched this and found this kit. I wouldn't hesitate for a second to purchase this again.

06 Uplander worked great! If I recall it has to be programmed correctly on the PC. Sorry I forget the details. It was worth using.

This worked like a charm for my aftermarket stereo. Had all the necessary wires and plugs, just make sure you connect the right one of the 2 smaller ones or itll seem like its not working. Made plugging in my back up camera a breeze and worked with my exisiting onboard mic the car came with. Definitely worth the investment

spent way to many hours trying to figure out the steering wheel controls...to this day i cant make it work...definitely not Plug-and-Play.

Driven this truck for about 15 years a never had a door/key tone. Fits a double din radio perfect.
