Another for the Sena TuffTalk. Have them and a Sena SR10 for the PMR. Can listen to music, follow satnav (best from phone - myRoute App), take phone calls, use as intercom with passenger and talk to other cars via PMR all with bluetooth and no cables connected to the headset - much easier to live with than headsets with cables plugged in!? Has anyone come across an App for the smartphone which works like a PMR but uses the mobile network? I am sure I read something about this last year but cannot remember where! Be interested to explore that more.
