Great product
Installed this on my 09 silverado and it is a great product a little confusing at first but this kept my onstar.

Good deal
It is very easy to install and if you have any problems thier techs are right there to help. They should have taken more time to make the chimes sound more like the factory's.

Great Product
Item worked great out of box with Kenwood DNX6980 in 2003 GMC Yukon with Bose system. Instructions were straight forward, made installation a breeze. This was my first install in years and all went without any hiccups. Would definitely recommend this item.

Disappointed
Unit delivers as promised. When using onstar head unit powers down. Program steering wheel control no longer cycles through preset stations. Not 100% satisfied, but unit performs basic description.
