I can't answer the question since my rig is a 2005. But I'm curious what is happening when you say yours is giving up? On mine the DVD player stops ejecting, it's a common problem as the drawer is moved by a rubber belt and not a gear. I found an o-ring replacement that works and have to replace it from time to time.
If the electronics are failing there is a small niche market of people who repair old stereo gear. I was looking for a subwoofer cone fix and yelp was popping up a few guys that repair electronics. You might try looking in your area.
