On longer trips with a BMW K1600B, it can be an advantage talking to your pillion or other passengers over an intercom system, also on trips in a group. With our Interphone-system it is also possible to establish a connection to the GPS system or a Bluetooth mobile phone. The intercom is easily attachable to the helmet. The latest versions of the Interphone devices are called Interphone SHAPE and Interphone SPORT. We are recommending the Garmin Zumo and TomTom Rider navigation devices especially for motorcycles.
