GM Navigation Install Inquiry
We installed a OEM navigation unit into a 2007 Denali, GM navigation part number 25797978.
When the truck is parked, the screen stays on.
What could the problem be? Is it install error, or a bad Navigation unit?

It has been to two different dealerships because we figured the first one didnt know what they were doing. Well, after being at 2 different dealerships, it has not been fixed!
Any chance both of the dealerships programmed it incorrectly?
The CD and map works fine, and the "theftlock" is no longer displayed.
