Metra WM-GM29-SWC Aftermarket Radio Data Interface and Harness General Motors 06-Up

this bypass module will provide and retain 12-volt accessory power, provide navigation outputs, retain chimes, retain steering wheel controls. super easy to install very clean have your aftermarket radio done in minutes

it was easy to install very satisfied

plug and play

When I plugged everything in and powered on my truck it didn't seem to be acting right. The radio didn't power off with the key off, the steering wheel controls didn't work, the lights on the stereo were super bright, nothing I did was having any effect on it. Then I disconnected the SWC module that comes with this installation package, turned off the truck and turned it back on and plugged the module back in. Then it started its learning process and in less than 30 seconds I had steering wheel controls, volume up/down, change sources, and the factory door and headlight chimes started working perfectly. So happy with this purchase.

Main part for regular radio didnt come with it but took me a couple of tries to get the wires to work with my radio and lets just say, I'm in love with my new radio. Had a couple problems with the harness at first. Person that was supposed to be doing my radio was busy at the time so I started working on it myself.

Does not work. Way too expensive for the quality. Bulky, Doesn't maintain steering wheel controls. Absolute ridiculous. It's the exact same as one of those cheap harnesses. Like the $15 ones. Only difference is this one has a little LED that tells you it's on and this one is very bulky so make sure you have plenty of room. Waste of time and money.

Wouldn't work tried it with 2 different head units finally ordered a better brand and everything worked great spend the extra money and get a crux much better quality

Box was opened and missing parts

Did not have the little box that it said it would have online to make my amp work in my car.

my package was torn up before I got it
