Where did you get this done? I would like to have our dealer call them. We had our 08 limited delivered today and had the Nav system added today as well. Wife and I needed roof rails for Kayaks so no Vista roof. However, you can't get nav without Vista on 08 from factory. We got in the car and none of the buttons on the steering wheel worked. No volume, no seek, and NO SYNC. They dogged around for a while, then said they think it needs a new download into the column's module. They did so and now the volume and seek work but still NO SYNC. They say they called Ford and Ford is aware of problem and are working on a retro kit. We are at a loss, because we can refuse delivery and walk away or hold our breath and hope the retro kit comes in eventually. We are extremely frustrated as we waited 6 weeks for a car that is not what we wanted. The whole point of ordering the car is that we were assured that the OEM Nav system was the same as the factory and that everything would work just fine.
I will also agree that the audiophile system is very flat with no bass. I hope that that is correctable as well.
THanks in advance for your input
