Comms for BMW System 7 Helmets

[Grumpy Goat]

Problem is System 7 helmets have a concave section where most comms or cameras need to be fitted.
Does anybody have some ideas to fix this.

Alan, where is this concave area you speak of? Outside on the left? I had a look at the web page on the BMW site and could not easily detect any concavity.

Any thoughts on going with a different helmet and better comm system?
