Mak - very impressive indeed! well done mate.
How long did it take you in all? where did you locate the unit and where did you install the USB port?
do you know if its possible to hook up rear screens to the same unit?
I'm considering the CID upgrade as I had exhausted all other options, but not sure if I should do this instead - what was the cost of the unit and what coding (apart from the video in motion) was required?
