My DAB on sync 3 keeps dropping out. Phoned the dealership to enquire about a service and mentioned this issue. Fobbed off with there are reservoirs in the area I live, yet I drive nowhere near them. What issue is it and what can I dump in the service guys lap to sort it out. I also get a sharp signal when the DAB is working then it dulls slightly then comes back. Can anyone here confirm it’s an issue Ford can fix or will they continue to give out bollox about reception.
