I recently had to replace the Shark fin GPS antenna on my wife’s Q3. Prior to closing everything up (panels, roof liner, etc..) I checked and everything worked fine with the new antenna (navigation, FM, satellite radio, etc...). A day later my wife started the car to go to work and got an error message “Antenna malfunction. Contact your Audi Dealer.” The only thing now not working is the satellite radio. Any ideas to fix are welcomed.
