Question: What the I on the bottom of the screen next to the "house"? I'm assuming it has something to do with nav.
Same build month, same upgrade path for me.
Both times I did it on my own USB drive. Took out my music USB drive (I have no NAV) and had a successful install the first time.
The CC buttons work (but don't show I'm making any changes, like light up) and I haven't tried the voice commands, but I'd suspect they don't work either since I have the exact same issues :( I'm in no rush to get to the dealer on this since the physical buttons/dials below are fine. I'll broach the subject when the car goes in for the rear taillight issues (paint being taken off by the light) later this week.
