Dimitri, it's been 4 days, has the update worked? Mine is at the dealer today. They told me they updated the software, but, I did not pick it up yet because I am waiting on a switch to fix my boot light. (keeps coming on with the boot closed.) I hope to get it tomorrow to see if the bluetooth is fixed. I will post the updated versions.Guys, I just got the car from the dealer, they put again a new 306 HU programmed directly from BMW with a new firmware update: MV-110.002.002, TV-110.002.002, which apparently solves the problem! This is something really new, they used my car as a guinea pig and haven't tested it yet on other (customer) cars, so I'm telling you its finally solved! No sound breaks, no bluetooth problems, no handbook freezing... The only thing is that the handbook takes some time to open and for a moment there you think "Oh, no..." but then after 10 sec delay it opens just fine. Well, I can live with that! So go to your dealer and ask to download the above firmware version.
For three months (since the day I bought it) I've been a pain in the ass to BMW and the dealer, and I think I acted a little like a catalyst to speed things up. Now the pay off is to have a bug fix with the new firmware update. I think I desrve just a little credit
