I'm sure there is a simple solution that I'm oblivious to, here is my situation:
97 855R, so I had an SC-815 when I bought the car. FM didn't work, but CD and AM was fine. I did the Aux to cassette mod for a bit but recently purchased Blaupunkt Adelaide 130 from Crutchfield with the included install kit.
Soldered the wires together and covered with electrical tape (would have used a better method but I didn't want to have to go out and buy something). Had one extra pink "Radio Mute" wire, as well as the steering wheel controls.
Plugged it all in and it powered up just fine, but I don't have any audio out of FM/AM or Aux. Is there something obvious I missed?
Thanks
