My 1995 Eddie Bauer Explorer with Luxury Sound radio died, no lights, no sound, no nothing. The radio has cassette player and CD changer controls with CD changer in the high-rise console. I verified both fuses were good. I pulled the unit and had 12 volts on both radio feed and memory feed wires. Next I pulled the top and bottom off the unit and found no damage or loose connections. I plugged the unit back in and confirmed voltage at multiple locations on the main board and it felt like it warmed up, but still nothing. I concluded the processor must be bad on the board.
I bought a new replacement from www.radiosandmore.com, good folks. I plugged it in yesterday and nothing. It must not be the radio unit. The radio only uses 5 small wires (maybe 16 gauge) as output/input. It doesn't even have the antenna coax plugged into it. Is there another main unit I should be looking for? I know there's an amp in the rear passenger quarter but I figured it can only affect the output from the radio unit, not any display or control function.
[updated:LAST EDITED ON 28-Nov-01 AT 04:19 PM (EST)]It's your amp. The amp is located in the back quarter panel, where your subwoofer is. Your receiver is only a keyboard and display with a cassette player, that's all. The amp in the back is the actual "brain" of the system. I wish you luck finding a new amp. An alternative way is to get an aftermarket cd player. That should save you a couple of bucks.
Billy you were right. The rear control unit is the brains of the system and it was bad. The folks at radiosandmore.com took care of me. I sent them my old front control unit and rear control unit and they sent back a refurbed rear control unit to go with the new front unit I had just purchased. Both units must be compatible, that is, have the same mods done to them. The lastest mods/revision is the "P3" mod.
