Cool Thanks for that, this is the rear camera i bought
http://www.ebay.co.uk/itm/Rear-View-...#ht_2571wt_698
and i thought with the Av it should work
but on the Av list inside the car there is Av 1 and Av 2 so if there is only three head on that cable with your link dose that mean that i would only have 1 Av or would i need to buy 2 Cables ?
