Yep ........ bluetooth from N95 Nokia to helmet. Tomtom GPS on the phone - voice directions via Ozzie Osborne (piss-funny).
You can have music from the phone playing and the GPS overrides for directions.
Also has a socket attached to the helmet speaker harness for a Nolan 3.5mm stereo input cable ( i.e. other MP3 device ).
With earplugs in, sound from the speakers is ok up to 100-120 kmh ( not concert quality ). It would probably be better, however the N102 suffers badly from
wind-noise.
You don't have the problem with MP3 player earplugs dislodging when you put the helmet on or while riding.
Not cheap - additional $400 on top of helmet price.
HTH.

I've spent over 40 years of my life riding bikes .... the rest of it, I wasted ..
If it's got wheels or tits, it's gonna give you trouble !
