Could you give me the number to that dealer becasue the dealer that I am going through says it can not be done. I bought a used Ford Edge Limited 08 with Sync, Navigation, and DVD head units. The dealer at the time told me the DVD was aftermarket and that the sync worked. He was wrong. Unfortunatley I bought the vehicle out of town and when I contacted them about the Sync not working they sent me to my local Ford dealership who can not seem to figure how to connect the sync again. Apparently the DVD wasn't the only aftermarket piece but the navigation is as well even though it is a genuine Ford unit. I didn't pay for a car with one option or the other, I bought both. They have agreed to pay to fix it but they can't figure out how.
