Is the hinged lid for the top tray available separately? I have the comfort dash at the moment and am mulling over the idea of having a screen pop up from there, triggered by activation of the parking sensors and connected to the reversing camera, using an Audi screen. I don't want to cut a hole in my existing lid so it's either get a second one or take a mould from mine and make a fibreglass copy if it's too expensive.
