How does the radio talk to the speedometer cluster?
When I bought the bike, the radio was good but by the time I got home (1000 mile ride) it was dead. No lights on the radio at all. The dash said NO RADIO and it wouldn’t turn on or off.
I bought another radio from the junker, just the radio, not the control buttons. I took apart the control buttons and cleaned them. There was no sign of water inside.
I had a good week with it then NO RADIO came back. This time, the radio would turn off and on and otherwise function.
I had some cross country rides to do and didn’t mess with it. I use the AUX input and plug in to the headphone jack. As long as I leave it on the correct input, the controls and radio work fine for this but I can't turn off and on the speakers when it's in this state. The control buttons all work, regardless of the NO RADIO message.
After storing the bike for the winter with the battery removed, I now find the radio display now turns on saying BMW, and then finally AUX, but none of the 8 center buttons do anything. Volume control does not show volume changes. I can't turn off and on the radio any more. I'm not sure where to start.
Also, I've got a problem with the EHCS where it won't activate after riding. If you turn the ignition off and back on, however, it works just fine. I've sort of gotten used to this small problem but I'm not sure if it's related.
