We have a "new to us" 2009 Jetta. In the process of transferring XM from old car to this car, we're not getting anything, just a low buzzing sound. XM said something is blocking the signal, and do I have a bluetooth device? Well, we DO have some sort of bluetooth setup in the header (looks factory installed?), near the controls for the roof, but no instructions on how to use it, turn it off, etc. Anyone seen this type of bluetooth setup and have any instructions how to turn it off so I can get my satellite radio working? Thx!
