The newest version is the Interphone F4 with many improvements compared to it's forerunner. Better microfone against background noise. Stereo headsett for better hearing, even with 180km/h. A communication with up to 500m distance is possible, you will need 2 F4's for driver & pillon rider or driver & driver. For traveling we recommend navigation systems by Zumo eg. the Garmin Zumo 550, Garmin Zumo 660 or TomTom, like the TomTom Rider II special for motorbikes. When buying, please look out for a special navigation system suitable for motorbikes. Other products are not waterproof and will not fit in the motorbike-mountings. The GPS mounting for the TomTom Rider 2 and the Garmin Zumo is with Bolt + Ram-Ball. You can mount all Ram-Mounts on the Ram-Ball. A brandnew product is the X-Navigator with 43 countries. The BikeCam2 is a high quality, waterproof and easy to use motorcycle video system. Combined with the Sony High Quality Solid State Recorder.
