Motorbike Helmet

I brought a tom tom sat nav for my motorbike , I’ve got the bluetooth adjusted to my helmet but it comes off after a while , I got advice from bike shop saying don’t tighten it up too much but it’s just annoying me , I went into a motorbike accessories shop called Rivetts and I noticed one of the helmets showed a fixed bluetooth on it , Im trying to find a motorbike helmet that will keep the bluetooth on it forever is there any helmets anyone can recommend? , hopefully that made sence lol

yep mate NOLAN do their own kit called the N.Com all the helmets are ready to accept it straight in think its over £100 + cost of helmet

Cheers Steve!
