Just bought 2 x System 7 helmets and BMW V3 comms systems. Music playback on both helmets is fine. Using the intercom is awful. When riding with both flips down and checking the mikes are in the right position I get a lot of crackling, hissing and intermittent electronic noise. It's not wind noise, I can differentiate between that. It is an intermittent problem, seems to get worse the faster we go (definitely not wind noise) and it only happens in my speakers and not the Mrs. We also keep getting the message 'devices connected' although the helmets retain their connection (possibly the connection to our phones). We've also both experienced an electronic high pitched screech in the speakers when we pass some vehicles-as if they are transmitting some kind of active signal. Has anyone else experienced anything like this? We've un-paired, re-paired, turned off bluetooth on the phones but no improvement. My helmet tells me my battery is at 80% after about 10 mins riding whilst the Mrs doesn't get that message for about 90 mins or so. We went from Nolan helmets and comms system to BMW and so far I'm mega disappointed with BMW, the Nolans were so much better. And apparently BMW don't provide a software update option for a Mac either! Any sensible advice would be appreciated before we try and get the dealer to look into it.
