Ah yes. You've hit on two funny issues.
The previous owner that I bought the car from cut the wires to the radio (I wish he wouldn't have cut them). He put an amp under the driver's seat, look under there, you'll see the wiring. Then look in the center console, you see the hole in the corner. There was an audio cable with an 1/8" plug on the the other end running straight from the amp into the center console...why you ask? so you could connect your ipod/iphone, etc. I took the audio cable and amp with me when she died because I could and I didn't know what her fate would be. You can hook one up and those sweet blaupunkts up front and in the doors will jam. If you don't have one, I can send you the amp with the title.
The dome light is indeed grouchy.
