Neotec 3 helmet & fitting 3rd party comms unit

[Freddyfruitba...]

I've just splashed out on a new Neotec 3 helmet. It's great, but I want to fit my existing comms unit to it (a Cardo Scala Rider Q1). Now unfortunately Shoei want you to buy their bespoke built-in comms gadget, which while very pretty and neat, is a cool extra £300 - that's definitely not happening. But because the Neotec 3 has a very thick rim (for their comms), it's pretty hard to get my unit to attach (even with a glue pad rather than a screw clamp).

If you've been there, you'll know exactly what I'm talking about! Before I start trying to 'customise' my Cardo unit, I Just wondered if there's anyone here who's been in the same boat and if so, how they've solved it?
