Does anyone know what the difference is between 55.00.650 and 55.00.750B? The "B" would indicate to me that it's maybe a beta version? .650 is what the dealer installed in my car a few weeks ago.
That's what I thought too. Dealer specifically told me 55.00.650 was the latest available version and installed it. Haven't had any system crashes after that. With v51, I had 3 or 4 system reboots while driving.
