Front and rear Camera rs6
 

Now i know Amar has a rear camera fitted in his so that should mean a front one is possible too. I have a spare tv tuner so is it do able? IIRC Amar mentioned James?

Definitely do-able, you'd probably just want it on an ignition live so you can swap to it at any point. But where would you mount it?

Or are you looking for a split style affair when reversing?

Split style :p

Well...in that case you need a lot more kit :) Some kind of tv multiplexer type unit :)

Hmmm surely the rsn-e can do front and rear cameras ............as in split screen I mean rear then front or vise virsa?

Buy a D4, get a birds eye camera and quicker than your car.
