well, the J&M company based in arizona are better known in the hardly davidson scene, the kit can be used with CB radio, family radio, cell phones, mp3 players, sat nav, and a couple of other things ive never heard of.
the unit has a built in FM radio which works incredibly well, its even compatible with the UK where as most american radios work on odd number frequencys only. a PTT button on the side for the rider to pillion intercom or CB radio is there but the mics are voice activated anyway. ive found the volume only needs to be at a 1/4 way up at 70 mph to hear it well so volume isnt even close to an issue with this system. visor up at 70mph on my GS still makes the cell phone easy to hear and for the receiving person on the line they tell me its fine whith a little wind noise, most wont have it that im on my bike if they call me. the downfall is having to fit your headset in your helmet. this normally means cutting away at your lid to make it fit. when everything is plugged in there is a system in place putting your mobile phone at the top of the pecking order follwed by the sat nav and then the intercom/your voice then the radio mp3 player. this system works brilliantly and even the pillion has the option to join in on the phone call. once fitted to your lid and you have the 16!! AAA batteries/rechargable lithium/12v car socket in place its as simple as mount on your tank bag or belt and ride away. very easy to control everything and all glove friendly.the intital cost is pretty high, but i can recommend this sytem as close to faultless (other than she can moan the whole trip if she needs to, and i do think it is a 'need' for her) one issue is the restriction on your look behinds when riding ive found the cable a little restricvtive.
mine arrived within 7 days with 45 quid tax to pay and once i fit it in or on to the right tank bag i will use it everywhere
