I don't have a phone, in fact I removed the fuse for the phone some time ago as part of the ongoing saga of battery drain.

The light just came on after I took out the FSR. I'll try and get a picture; it's part of a vertical array of rocker buttons that set the audio, time and date, BC etc. it's the BC one that has the red light, the bottom one.

My manual says check the Radio or Onboard Computer Manual, neither of which I have. I was hoping to find them on this site but haven't been able to yet
