Default 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.
