well I haven't contributed much to this yet but I've been working silently in the background

I've got a system set up as follows now:

one Nitemax body with the image on the screen flipped horizontally.
one switch on the body to power on and off the CCD(s) so the video out becomes video in.
two CCDs connected via a selector switch and both mounted externally along with a single set of IR LEDs.
one of the CCDs is a standard B+W one and will be used for forward facing night vision, the other is a colour one with its image flipped onboard so it appears the correct way round on the screen
the switch will be replaced with one in the gearbox or at least linked to the one already there so that when reverse is selected, the colour camera is selected and as the image has been flipped twice, the image will appear the correct way round when used as a HUD.
The video in is connected to a car pc so I can switch over to sat nav display on the HUD, this is switchable to an output and that goes into a capture card which in turn goes to the pc.
I will hopefully find a way of overlaying the sat nav on to the night vision video feed so I can get night vision and sat nav on the HUD simultaneously, but I'm currently having problems getting the damn capture card to work at all

One question though, when the PC data is displayed on the 2.5" LCD, it is B+W. I know the screen is fine as it displays colour from the colour CCD as well as from my digital camera as a source and a VCR. Why is it doing this and can it be fixed? I've tried all the range of TV signals (and in turn frequencies) to no avail.
