I have a much cheaper set of intercoms that I can get to link to my phone, talk to my pillion, get stuff from the satnav and talk to another bike. Cost me €56 a pair two years ago. But the newer ones link to 3 other riders, have fm radio, have vox commands and are much more functional.
But, another £300 more functional???
We are going to Spain with another couple later in the year so a four way intercom would be useful, but if I think about it, not at that price.
