I am hoping that one of the sharp techs can help. I havea 2009 Silverado. The preious owner had his dealer install a Nav system. He had the bose system from the factory. I think they pulled the Nav from a Tahoe. Radio works fine. Nav seems to be alright. BUT: The tech had to program it as a Hybrid ( or it was from a Hybrid?) The door chimes and turn signal chimes do not work and the bluetooth does not work. AS well their is no clock display. I have been told that a GM tech can put the truck on the tech 2 and get it to work. I have had it to 2 dealers and still nothing. The techs call the GM techline and of course they will not help. I am willing to PAY fo the solution to this problem. HELP please!!

There was a guy on ebay that claimed he could reprogram these units to whatever you needed (including your VIN so a trip to the dealership wasn't necessary). I have no idea if the guy is legit or not, but have no reason to believe he isn't. I wish I could remember his name. I'll see if I can find him and post back.
