Bluetooth system 5
Hi, Sorry for the delay in responding it works very well, the battery life of the helmet has not been a problem although I have not used it on a full days touring todate.
The instructions are specific however and BMW says you must discharge and recharge 20 times before the full 6 hours + will be acheived, I guess you could do this in the house if you wanted to.
I have no problem with noise although I have a taller screen.
The TTrider overides communication with pillion as does the telephone .
I have been asked the question about the stereo before and I checked ,and have been assured it is stereo, ready for the unit bmw is going to launch for ipods etc.
The other nice touch is by using a pama viscount hands hands free blutooth
kit I can use the TTRider in the car without an earpiece.
Cheers
