I don't fancy the idea of being joined to the bike with a wire either, so like Graeme, I've gone the Scala Cardo route; I also have the G9 and can second his recommendation; it's great for music, bike-to-bike intercom, sat-nav and phone—loud and clear, though the intercom range isn't noticably better than it was on the G4, and in reality it's nowhere near the claimed 1km. It should be possible to overcome this by linking a PMR handset to the Scala via bluetooth, but I'd like to have some confidence it's going to work well before spending yet more money! You could always do it with a bluetooth adapter, but there are now a couple of PMRs that have bluetooth built in, such as the voice-operated Interphone TRIBE or Midland G8, which is PTT with a button on the handlebar. It would be tempting if I knew others were also using such a system successfully—do any of the other riders in the group have such a thing? I wonder if it would be possible to borrow some to try out before buying.
