I really don't like the idea of not having a detachable faceplate either. So I came up with a pretty good idea (well to me anyway) the other day about theft prevention for my touchscreen indash unit. I plan on making a cover that simply snaps on the unit disguising it as a plain dash panel, maybe with the Mitsu logo on it or something. Should be pretty simple to make, and wouldn't attract attention. Out of sight, out of mind...
