I'm at the point with mine that I'm not sure I'd update it. It does the following still,
- Occasionally sees a car in the left lane with ACC on
- Still doesn't know the right speed limit on speed adaptive ACC (I just don't use it I can adjust speed myself)
- The temperature Sync un-syncs it self every time I turn the car off (this really bugs me)
- I get an occasional Traffic Information not available which I researched as the Car 2 Car thing
The only thing that would get me clamoring for an update is number 3 in the list above!!
I'm on 1666 and had the SOS OCU update and the Keyless entry fixed in September!
#1 I think is fixed with 1668, but you might as well wait now.
#2 is only fixed with the forthcoming "big fix"
#3 is not a bug, its a feature - don't think this will ever get changed.
#4 Yeah thats just car2x having some sort of interference problem
On top of these problems, I've got:
#1 infotainment reboots pretty often
#2 sometimes no sound
#3 bluetooth doesn't connect to my phone when i get it (I've got a hack to fix that, but also opening and closing the driver's door does the same!)
#4 random bongs about things not working - adaptive lights, lane assist, parking sensors, exit warning - worse when its cold
*sigh*
