I'll be doing something similar. I have a Honda and the same plate Tony (tfabris) uses. But I'm going to modify that plate to be able to hide the empeg while it's in the dash, as well as be able to cover the space when the empeg isn't there.

The idea is that if I'm at a store or the movies or something, I don't have to worry about people seeing it and deciding to steal it because it looks cool. I want a completely stealth install.
