I have had my current full-face AGV helmet for about 8 years now and it's starting to show it's age. I've started shopping around for a replacement and one thing I'd like is for my new helmet to Bluetooth capable. I want to use Bluetooth for GPS navigation, taking calls, rider-to-pillion communication and maybe music on longer trips. I've done a fair few hours of research on the net (including previous posts on this forum) and it seems that my options when it comes to full-face Bluetooth helmets that are available in Australia are the BMW System V or the Nolan N84 with the additional N-Com bluetooth kit. Both of them seem to be a bit pricey though. Can anyone suggest any alternatives? For the pillion the best option seems to be the BlueAnt Interphone. From the reviews that I've read it's got much better sound quality than the Scala Rider unit. However, I'm worried that the Interphone will only work for other Interphone units for rider-to-pillion communication. Does anyone know if this is true? If so, is my best bet to just buy a non-Bluetooth helmet and use 2 Interphones? The main thing I don't like about the Interphone unit is that it is mono only. One of the reviews that I read said that a stereo version is planned for release but I haven't been able to find it. Does anyone know if it is available anywhere?
