what uconnect version are you on. I had a problem with it not recognising my USB drive after an update, found it was a bug and was fixed in the next version.

edit: I'm trying to avoid that rolling in park recall, it stops you from being able to move the car with the door open, which I like to do sometimes offroad. Really, if you aren't american, and you know how to put your car in park, you won't have a problem.
