HORIZON12 Chevy Silverado/GMC Sierra (2014-2018) 12.8" Radio Plug-&-Play Kit

Good product, very detailed with easy to use funcions. Only bash is the IGo should be in a kit when spending 2k. The instructions have you install the GPS, but need the IGo chip for it to function.

So far a really nice and responsive stereo

Great setup looks awesome and you get all the access to your car featurs except the valet/teen drive mode. I wish the instructions for various setups were readily available. For instance it comes with the lead to use the factory sharkfin for extra xm radio adapter you need, had to figure that out on my own, same with other accessories. Seems like it may be possible to do more than is advertised. With HDMI, accesories, video etc.
