thought you'd like to hear the latest.
took the car to the dealer and they replaced the control module. I then reconnected to Sirius and it worked for about 30 minutes, and again failed, showing "searching for signal". Called Sirius and they tried again to send a signal and could not.
the dealer paperwork says they "ran SDS test and found Code D241". they then "performed electrical test of Sat Antenna and found ok". then they replaced the module.
Bottom line...it's still not working
