Have to say Goodbye, I upgraded to OGM1. Bluestar has been good to me and I found the service to be excellent.
But I went with the Advent OGM 1 for my Silverado. 7.5" inch screen, backup camera, bluetooth by Parrot, restores GM XM and Onstar service, GPS by Igo, IPHONE, IPAD ready, USB input. and it is plug and play. No wire adapters, just swap out the factory radio and install rear camera. Easy.
Thank You BlueStar for the years of good service.
