Nolan N-Com E-Box Intercom BT3 Kit The BlueTooth 3 Kit includes the E-Box, the battery, the battery charger, and the seal. It is used for wireless connection from helmet ot helmet, or between a helmet and other Bluetooth equiped devices, such as a phone, GPS, etc. The BlueTooth 3 is stereo for music (when used with the Basic Kit 2 ) and allows the rider to control his music source from the helmet (skip song, mute, etc). Thanks to its multiple circuits, it also allows two helmets to be paired together for rider to passenger communication and for a cellular phone to be paired to each helmet at the same time. BlueTooth 3 works from bike to bike, with a distance of 500 meters. This distance will vary with the environments, becoming longer on flat, straight, empty roads, and becoming shorter on mountain roads, in cities and on busy roads. BlueTooth Kit3 is the newest version of the Ncom BlueTooth E-Box, to be used with the current Basic Kit2. It offers the same integration level as previous versions plus Rider to passenger communication via BlueTooth Bike to bike communication between two BlueTooth B3 systems up to a distance of 550 yards FM Radio with RDS function (to stay tuned to the same radio station for the entire ride), with 6 pre-settings for your favorite radio stations Other devices can be connected to the B3 Music players and other devices using a standard headphone jack can be connected via a wire and other BlueTooth enabled devices such as a cell-phone and a GPS can be paired through the BlueTooth connection Firmware updates as well as presetting of the radio stations, volume controls, etc. can be done by connecting to a computer via the jack-to-USB cable (included) with the N-Com Wizard program
