I have a question regarding Bluetooth and helmet. I'm looking into buying a good quality dot and snell approved helmet, the one I have my eye on is the Shoei RF-1100. I would like to get bluetooth for it, the reason being is that every couple of weekends I am on call, and it is important that at all times I am able to hear/answer my phone. I don't need it for listening to music, and it won't be a distraction; I simply want it so that in case work calls, I can answer, tell them I will call back in two minutes, and pull over somewhere safe so I can work remotely via laptop. Now I would like to know the easiest and most reliable kits that would work with that type of helmet (preferable not ugly looking or bulky either) and easy as possible to use. I also don't want it to affect the integrity of the helmet or dot/snell approval. Does anyone have suggestions for this?
