See, I have the exact opposite opinion. I've been using CoPilot on my S2 Samsung with Bluetooth to my SENA since last season. Bluetooth integration is seamless. Turn by turn, phone calls, and the mp3 player integration work perfectly. Hell, the re-route is quicker than my old Garmin. It was a little tougher to pre-program routes until I found RouteConverter for the PC which saves in .trp format for CoPilot. The only issue I have is not being able to manipulate it through my gloves. And even then, sometimes a long press will work.
