I'm looking at a bluetooth unit for my helmet. It's time to add the ability to listen to nav directions from my phone. But a dumb question, do the units always/only mount to the left side of the helmet? I know why, it's not the throttle hand. But in my case, well ya know, I can't go left. Is this one ofthose things I gotta live with it it on the left or is there an option on the market to mount on the right?
