All sounds great ! I see you have added additional photographs to the original Post. Any pictures from the back?
There appears to be 2 parts to this Stereo, where the main body (minus screen) can be positioned elsewhere (hidden out of view), with just a ribbon cable up to the display?

Will you be stocking just the custom mount, for that specific Android stereo, or as a kit, including the additional wiring / cables necessary for this complete install.
Look forward to progress updates.
