Judging by one of the images posted above (and comments made), the back does have a recess to fit the lens.

Looks good to me. The only polish I'd make would be to get the top and bottom edges more similar in thickness - though this may just be something hardto judge from the image attached (don't know if some of the bottom part is shadow area).

The curves work well, including the top right.

I thought about trying to make a fascia specific to my car which would not have a recessed back. Because of the way the console is designed, a head unit can be made to fit in perfectly flush. most aftermarket head units aren't designed like this and leave awkward gaps around such consoles. The stock BMW head unit has a fascie that's just a simple rectangle around the outside. I may take my previously modified stock fascia and using more epoxy make some additional mods.

Anyway, I'm really looking forward to seeing these new models in person.
