Upgrade your N-Com Basic Kit to adjust volume and answer phone calls directly on your helmet, or communicate with a passenger. The Intercom Kit includes an intercom wire for connecting the rider and passenger. The Bluetooth® Kit allows wireless communication between the pilot and passenger (must be installed in each), and wireless connection to Bluetooth® phones or other devices (only one wireless device may be accessed at one time). Both of these kits include a on helmet control unit, battery and AC battery charger. The Basic Kit must first be installed to use these kits.
