Am about to do a long distance trip with a few mates and need to be able to talk to each other. A couple of us have autocoms, one has a starcom and a couple have Bluetooth systems, n-com and something similar. The autocoms and starcom can use pmr radios, but as my autocom SPA kit hasn't got a Bluetooth module (my zumo is wired and mobile BT to zumo) is it possible to get a Bluetooth module and then run bike to bike? What's going to be the best way for us all to communicate? Mobile phone is too slow and cant reach us all. Especially in the middle of Scotland. Any suggestions?
