Easy Install and great price.
Very easy install for a 2012 Silverado w/o navigation system. Easy to understand connection via color code to the new radio harness. The only odd item was using the solid blue wire to the blue white wire for amp power. Just have to read first to ensure all wires are correct. Great price and easy install. Would suggest buying shrink tubes and sodier the wires vice twist connectors or crimp connectors

2011 GMC 2500 Denali.
Worked great after I figured out that there was a second programming option for alpine steering wheel controls, for Alpines with wired steering wheel control inputs. Also we had to move the remote turn on to the ignition wire, because Alpine doesn’t have enough amperage Metra tech said.

Glitch
They work like they’re intended to. Sometimes they kind of glitch but for the most part they work

Stereo and stock sounds are working
I tried a different harness that came with a dash kit and the blinker and door chimes disappeared because that kit did not have the data interface. This kit made the sounds come back. FYI, It does sound slightly different than stock.
