It's not that simple. From what I know, the CMU basically takes the analogue (!) camera signal from the rear camera and displays it in an overlay, with minimal (or no) processing in between.

To be able to store the feed, it would need to digitize it, encode it (to H264 or MPEG2 or something), and make it available somehow. It doesn't do any of those things, and I wonder if it would actually be capable of doing so to begin with (especially the encoding would take up a lot of processing power, unless the CMU has hardware encoding on board, which I doubt).

Oooh you are right.. I didnt think of that..

On ebay you have dash cams which enable you to connect a rear camera in addition to the obvious front.. Do you think it could be possible to connect the OEM rear camera to that dashcam?

Else you will have 2 rear cameras, one the OEM one, and the other from the dash cam.. If ever there was this possibility of extending the functionality of the rear camera we already have, it would be a great value added i think

We know the OS is still controlling the screen when the dashcam is active so it should have easy access to the image in the form of a screenshot. If this can be done off-screen as well then an app could maybe store pictures to a USB drive. My guess is it would slow down the system quite a bit though.
