Finally!!
Just got the car back and it has the 3.10 version now! Holy cow!
It is considerably more reliable with my iPhone. Button presses are much less lethargic.
Took them 5 hours to get it done today. That's in addition to the 8 or so visits at 6 hours each. Clueless is an understatement. Glad the service adviser was invested in satisfying the customer.
Case closed...
