Replacing head unit
Dealer is replacing the head unit this coming Saturday. My GPS got lost & the car phone keeps saying it needs service. They tried the latest s/w update and it froze at the Air Card step 3 times. They gave it back with a completely blank screen. No radio, no controls, etc. I was able to get the radio to reset by pulling the update USB I had in the reset step. Question is: what about my uConnect access & SiriusXM. Will they automatically restore that. And how many more head units will I need????
