Been messing about with it this morning.
The phone (iPhone 3GS) will find the helmet & Sat Nav ( Navigator lll plus). I can receive calls on phone & listen to music.
When trying to pair the nav to the helmet, it wont locate it, so I can't hear voice instructions. It will pair ok to the phone, as it shows all contacts from the phone memory.
Its the BMW Communication system fitted to the 6
