I use the Nolan with their N-com System, works well. Clear and loud enough at speed.
I have it connected to tomtom and mobile to tomtom also Bluetooth to Passenger intercom, if you want there is also a socket to add MP3 player to the set up aswell. The original set up is mono but the second generation is now stereo, both work with each other. And the helmet setup bluetooth remembers those its been connected to so after initial setup it's easy to change the priority on compatible items.
