I have a bmw system 5 (or 6) helmet. So full-face, flip up with internal sun visor.
(probably all the wrong lingo, but you get my drift).

My friend has two Sena SMH10 communicators. got one on his Shoei helmet no problem.

when I went to put it on the BMW helmet, it interferes with the operating switch for the internal sun visor. Of course I'm not compromising on that.

any suggestions on how to install. If it is too far back, the boom mic won't' reach the front of the helmet.

I know there are communication devices for the BMW helmets, so it can't be too much of a mystery, but I am at a loss and would appreciate any thoughts that can help.

Want to be able to pair to my buddies SMH10 too.

thanks in advance for your suggestions.
