I had mine in for s/w updates last week and the dealer said it was updating various issues for around 6 hours.
My issues were very intermittent so we'll see if it has resolved them, the screen seems to be more responsive tbf. They didn't change any h/w.
One thing I noticed, that I thought it would get resolved, is the temperature SYNC still gets reset each time I start the car.
Q. Anybody who's had the s/w updates - does your SYNC now work? Not an issue at all but if that hasn't been resolve I'm wondering if the issues I've had may still be there.
Cheers
