I've got a factory-installed RNS-E with bluetooth in my B7. The RNS-E works fine, but the for the past two weeks, it is reporting No Telephone Available. It also started running down the battery at the same time, and I suspect it's a faulty bluetooth unit. Now, I know the bluetooth module is buried under the passenger seat. Does anyone know if there's a relatively easy way to unplug the bluetooth module without having to remove the seat and tear up the carpet?
