My salesman told me two things would most likely happen....once. After that, he said they rarely happen again. One is if I shut the car off while MFT is downloading an update - it will need to be reset (something like that). Problem is it does not tell you when it is in the process of a download!
Second thing is he said the phone will get caught in a loop. He said it always seems to happen ONCE, but after that never seems to happen again.
I think both of these things will require me to head to the dealer. No biggy. Since I expect it, it won't upset me when it happens.
