Does anyone have any idea why the oem navigation screen won't work after replacing the bose head unit with an aftermarket one. I basically replaced everything, head unit, amp, speakers. When using the aftermarket wiring harness for the head unit I didn't bother connecting the amp ground, or the amp power connectors since the factory amp is no longer being used. Could this be the problem for the navigation not turning on? I hear the beep once in awhile, but I'm not sure if that comes from the screen or somewhere else. Any ideas?

Thanks for the help in advance.

Never mind. After hours of trying to determine the problem, there was a loose connection between the dvd reader and the navi screen.
