Review on Enhanced Car Stereo Installation Kit: GM LAN29 Buick Chevrolet GMC Pontiac Saturn with Dash Kit, Wire Harness, and Antenna Adapter – Important Notes Inside by Michael Custodio

This kit worked great on my 2012 Sierra, if you just want to install the base kit then this is what you need but the red power wire must be routed separately from the wiring harness also included in the kit and this wire only needs to be connected so that when the key is turned the radio also turns on. The Hardest wasn't too bad, not the best, but pretty good, if I had to order it again I probably would.
