SUBJECT

SITUATION
Some customers may complain that in certain geographic areas the SIRIUS Satellite radio cuts out up to 30 seconds at a time.
CAUSE
SDARS antenna module reception characteristics
[NEW]CORRECTION
If possible, duplicate the condition together with the customer.
Compare the customer vehicle to a similar vehicle (6 Series) in the same area.
If the vehicles act differently:
^ Check the antenna coax cable from the SDARS receiver to the SDARS antenna module
^ If this is ok, check for a defective SDARS antenna module by parts substitution
^ Only if the antenna from the known good vehicle improves the SIRIUS Satellite radio reception, install a new SDARS antenna module.
