That is very cool... you could totally start up a little side business producing mods. I would love to get a sunscreen like that for my POS Axxera radio. When I have the back-up camera on I can hardly see the picture feed when the sun is out, the bathroom light is on, or my daughter has her iPad on in the back of the coach. This is my way of saying I hate the Axxera system.
Seriously, very cool what you are doing there!
