Beware Mercedes Benz owners (bluetooth issue)
If anyone is having bluetooth connectivity issues between their BB10 Q10 please be advised:
At this time, Mercedes Benz does not support OS10.2.1
If you are having problems, that is why.
I ended up buying a new Q10 with OS10.1 and did not do the upgrade and everything works fine.
Here is the Mercedes link to supported mobile devices:
Mercedes-Benz Bluetooth Connectivity
I have not been able to contact Mercedes yet as to when 10.2 will be supported.
I'm assuming you will have to make a trip to the dealership to get the upgrade (not sure)
