I have a 97 540iA and I just purchased the WDS wiring diagram DVD. I was hoping it would have an electronics schematic for the radio so I can find the solder points for the FM joints. I am having trouble with the FM going in and out and after reading many posts I am 99% certain it is the solder joints which have broken loose. The WDS DVD has the wiring diagrams, but no schematics of the actual electronics boards and circuits. I did find a schematic for the MID online in pdf format, but no radio schematic. Any ideas where I can find the schematic online? Or does anyone have it and can send me an electronic copy?
