Hello all, I recently bought a nav unit off ebay which I believe to be a 2010 model because it has the usb. I installed it in my 08 Sierra and got the blue theftlock screen. I took it to the dealer to have it unlocked and he couldn't get it, then I showed him the bulletin where you put in an 06 monte carlo and the unit unlocked. When it restarted it showed the GMC logo on the screen and then showed the clock in the middle of the screen. When we tried to turn it on it wouldn't do anything. I pushed every button on the unit and nothing changed, just showed the time. I did notice the time was an hour fast, not sure if sets the time from satellite or if that was the time from the person I bought it from. Has anyone ran into this problem where it shows the clock but won't turn on? The dealer has no idea what to do now. Suggestions would be appreciated. Thanks.

For any of you wondering, a 2010 navigation will work in a 2008 truck. I sent my nav off to a guy in California, he charged me $135 and completely reprogrammed for my truck, now it works great!

I sent it to CPS Audio and Video in California. He is very quick and great communication. His email is cpsaudiovideo@yahoo.com and his phone number is 707-588-9300. And I bought the nav unit off ebay for $500.00.
