Cadillac Repair: Cadillac Radio Repair, radio repair, nav system

Question
I have a 2000 STS with integrated Navigational program.  The radio won't pick up FM or Weather, just AM.  The CD unit, while not working well, still plays.  
Can you give me the part number for the radio and can you tell me if it needs to be a special radio because of the integrated Nav System?


Thanks very much

Answer
Hi John, I don't have access to a parts manual but a phone call to the dealer parts dept should be able to determine if the radio is special or not. Sometimes the antenna lead gets unplugged inadvertantly and that could cause AM only. I would try removing the radio and plugging in a fender mount antenna and see if the reception returns. Maybe you might spot where the antenna came unplugged. Bill
