iPhone 6 tethering to the online function works fine on my 2013 W212.
It does however need to be the NTG4.7 system to work as I believe it is not compatible with the 4.5 system. Changed to 4.7 in late 2013.
Just need to change my provider from 3 now as the signal coverage in not good near me..
Same damn problem here. I have 4.7 and iPhone 5s. Says phone Wont transfer data and NO one seem to have a clear answer. For example Phone transfers data fine when conected with USB to a computer for example. So must be over Bluetooth the problem is. ?
