my dad has got an auto com system, on his bike for him and my mum. i tried it when he first got it an was rather impressed. you can hear it it very high speeds even with the loud exhaust. the main thing i like about it is if two of you have it then you can plug walkie talkies in and have a chat bike to bike, rider to rider and pillion to pillion which i think is a well cool idea. two or mor bikes being able to talk all round. music and phone are also able to be pluged in. atuomaticly cuts the music when you talk and plays gain when your finished. not cheap but definetlythe way to go
