I don't have Blue Tooth, I have Autocom that connects to my CB, GPS, Radar Detector and XM radio. Wife also has Autocom on her bike with CB and XM radio. By using my CB I can tell her where to turn, warn of radar, also talk about gravel on road, rest stops etc. Once when we were in some major city we got seperated by trafic and signals, by using my GPS I was able to give her instructions through the CB's as to where to turn and meet up with me. Another time traveling in Vermont my riding buddy and I were in some town and using my GPS and CB I was able to transmit directions to him as to where to turn next to get us to a road we were looking for. Very handy tool We do not chat just info exchange. When traveling alone, I can get road info from and hidden laser police raps fromtruckers while on major hiways and also road construction issues. Also using CB, allows me to talk with Goldwing folks and also some Hardley fellows with CB's built into their bikes. When my wife rides on my bike with me, she just plugs her helmet into my Autocom and we have communicats on bike. Been useing Autocomm since early 90's with CB. It is trickey to set-up but when set-up properly works very well. Two other fellows that ride Hardley wan-a-be bikes dont want this type of sytem because they do not want wires to the helmet. As posers it would ruin the effect of the cruiser ensamble. I find it a pain in the rear to try to communicate with them. On one trip my Buell broke down and the fellow I was with did not know about it far a long stretch because we were on a winding counrty road with lots of woods. My wife knew immediatly because I was able to CB her. Also if I need to take a break (My urologist says that I have a trophy prostrate, I know to much information), I can radio as such, with those fellows that think form is more important than function they just motor on in their blissful oblivion, and then need to come looking for me in the nearest rest room. That is my story and I'm sticking to it.
