I’ve had a car radio on the scooter for many years. The sound is transmitted via cable to the 5 cm broadband speaker installed in the helmet, which works quite well and does not decouple the outside noise like the headphones. Since last year this radio was broken, I didn’t want to replace it with a simple radio receiver anymore but decided to use a 7″ multimedia player. r Looking back directly behind my scooter through the existing mirror was simply too little. So I have attached to this device a rear-view camera to the scooter and thus always have a third (electronic) rear-view mirror, which is very useful for me. Multimedia means, I have to listen to a lot of other possibilities of playback besides radio, so I can play music, pictures from Micro SD card and if it should be also movies. Also a playback would be possible r USB stick. Only what I don’t have in this device is an integrated Navi, because I already have a separate Navi, which can be mounted higher above the multimedia player. Sound outputs are available for two helmets and these can be connected and controlled separately. Now I could have been satisfied, but if you are already there, you want to exhaust everything else. So now speakers had to be connected to the scooter and because the small upper speakers the sound n A subwoofer has not been installed at the bottom. All loudspeakers can be easily removed as required. I liked my multimedia expansion in every way and I am fully satisfied with sound and all the possibilities.
