I just purchased a (mildly) used '07 about a week ago.? In the past week, my XM reception has been lost due to "communication failure" and restored three times.? The condition lasts from a matter of minutes to hours.?
During each episode, the steering wheel volume, channel up, down, etc. controls are all disabled.? They will not function with AM, FM, or CD sources even though the sources all play fine.?
Does anyone know if the steering wheel remote unit's signal to the head unit has anything to do with the XM antenna?? Is steering wheel remote available with the stock head unit?? My dealer is puzzled and waiting for it to fail completely before they'll troubleshoot.
