Look what I just got in the post

I'm have machined an alloy mount which will then be attached to the faceplate with grub screws. Will then wrap the whole lot in carbon. No mould.
The alloy mount is strong enough to hold the Garmin, the carbon is mostly for looks, and to sthengthen the bond with the faceplate.

Sounds good. Post some pics when you've finished it. Tidy.
