2003 DTS Stereo/Nav won't power up
 

Good Morning.
I just purchased a 2003 DTS, and love the car. It has the Bose Touch Screen/DVD Nav System in dash with the CD changer in the glove box.


Sometimes when I start the car, the head unit will not power up. However when I pull and re-insert the NAV fuse on the fuse panel, it powers right up.



I've noticed that this happens when the key doesn't chime when I insert it into the ignition. Also there are no beeps when I press the memory seat buttons.



What could this be? I'm already getting tired of removing and putting back the fuse.



Any ideas or insight would be greatly appreciated.

Thanks,
Pose

Soooo nobody knows??
