After something like a Tom-tom for my bike and Car . So what ever I buy will have to be easily moved between them. Ok, I have the BMW K1200R and it has a socket but will that work for these devices ? Also how would you go about getting earphones etc in the helmet so you can hear the instructions and / or mp3's ( helmet is a Nolan Classic N-Com N102...well will be when I get the parts that fell of replaced ) And yes the amount of research I have done is sfa because I believe the intelligence and experience in this group will give outstanding results ( thats my groveling for this year done ) thanks will
