Was attacking the dash today to get the reversing camera sorted.
took this, I have the unit near the gear stick, it is now stuck to the side of the panel that surrounds the gear stick/cup holders.
It takes negative from the aerial signal, so all it needed was a positive feed (red) which I took from the cig lighter right next to it.
Sorry only got one pic but it's a great unit and the sound is crystal clear, have set it to 88.1mhz as have no station here with that and never ever have a problem. The only thing is you loose all radio signal when ipod plugged in but other than that, great piece of kit for the money, simple and easy to fit.
Also gave me some time to clean/hoover in there, amazing how much stuff gets in there! so all clean now
