I have a 2011 Silverado and I just installed the Advent OGM-1. I paid the same price as the other member listed. Walt is very helpful and there is a ton of information on the website that is available to you...once you order. I have the factory USB port working with the Advent. Bluetooth works perfectly from both the Advent and the factory. Walt is super to deal with and I am sure he would be happy to answer any question that you have....he did for me. This usit was super easy to install. I have never installed a radio before and it was a breeze!!
