We have had our B Max for six months, we have had a number of little problems but the one that I cannot get an answer on is the SYNC system, I can sync my Nokia Lumia 800 phone, it pairs but then drops out, the dealer is at a loss, Nokia have checked the phone and they are say it's ok, Ford/the dealer are say the car has all it's updates, but my phone still drops out, were/who can I take to at Ford. Maybe this is a Bluetooth problem, does anybody know we're I can go for help?
