Here is one for the group that has me and my service tech stumped:
First, before anyone refers the FAQ and the HOW I did that first and the following IS NOT what I have:
Found in the FAQ:
" My radio display reads "NO RADIO" after it gets wet. What's up with that?This is a very common problem that can occur when water gets into the connectors under the display. Many times it will clear up on by itself but the best remedy is to remove the stingray and put dielectric grease on all the connectors. Another common cause is hairline cracks in the rubber boots on the radio controls which allow water to penetrate into the display (called the Remote in BMW-speak because it remotely controls the actual radio). Check these boots frequently.
NOTE: This problem may also result in the display showing "PHONE" instead of "NO RADIO" and/or the radio playing with the ignition OFF!"
IIRC I think this problem may of happened years ago and I did take the precautions and put the dielectric grease on the connectors and all has been well since.
My current (pun intended) problem is:
- I get a "NO Radio" display when I touch the controller to turn on the radio.
- I do not get any radio reception however I can play a CD in the stingray CD changer (yes, second radio in 6.5 years with the first radio being a cassette).
- I can not change tracks or adjust the volume with the handlebar or passenger controls playing the CD.
- All connections have been checked, re-greased, and re-connected.
- A second controller, my old radio and another used radio plus combo-wire loom have been tried and still the display reads "No Radio".
- BC3 Comm system works perfectly
My question is:
Has anyone had this problem? If so, what was the fix. Can anyone tell me if there is a loop through the handlebar controls that if there is there is an "open circuit" might cause this problem? The handlebar controls are the only part that has not been tested.
My tech is going to open a "COBRA" inquiry through BMW technical support to see if engineering has any knowledge of this issue. In the meantime I'm worried about the main wiring harness and some possible issues that age and time may have had an effect. My only frustration is not having a wiring schematic and diagnostic tree to help us diagnose this thing.
BTW: I had the "NO RADIO" pop up once last summer on a weekend ride before leaving for CCR. The circumstance was a twisty mountain road (one of the best ones here in Oregon too ;-) and I hit a dip from a sinking grade. The total suspension bottomed out and the radio quit. I was thinking the radio loom came unplugged, however the radio came back a few miles later and never gave me trouble since. To be preemptive before CCR I did my Level 2 service and took great care to inspect all under-tupperware wire connections, clean and use dielectric grease, before putting her back together.
TIA for any help offered and if the moderators want to move this to another forum be my guest. I wanted to reach the widest audience with my question. Thanks for the bandwidth.
