So, I was in a hurry the other day and neglected to turn off my headlights when I got to work...

Needless to say, when I came out to go home, the battery was obviously dead. Got some jumper cables and a friend and jump started the Max. From that moment on it turns on, runs the cassette deck (I have a cassette to mp3 player adapter) but the radio controls don't work and there's an intensely irritating interference coming through the speakers that increases in frequency with the rpm's of the motor. Strangely enough, the volume control still works too.

I must have blown some circuit in the factory radio. Very disappointing given that I bought this '82 diesel off the original owner w/65k miles on the odometer!

3k miles later I need to find a replacement radio. I'd actually like to keep it factory rather than cut the console to put in a cheap aftermarket unit.

Thoughts on where to get a replacement factory radio or some other creative solution?

I've thought about hiding an aftermarket radio but the center console and the glove box seem too small...

 

did you check the fuses? could be a chance you just blew the fuse

 

If it's related to RPM, you may have an alternator whine problem. It's caused by a malfunction in your ground loop. But first, try checking your amps. Then reground your HU if necessary.
