Hi guys, im trying to do this install as well, and i have a rough idea of which wire goes where, but im not getting any result. So far my RCA plug is cut open with three wires. I know which colour is pos, neg and ground. I connected my + to the red wire on the back of the unit, the - to the grey wire and my ground to the white wire. Is this correct? By the way my car is not a facelift model as i am doing a complete swap from my 6 stacker to a factory sat nav, so i have no 24 pin plug, so i have made my own connectors for where the 24 pin plug would originally sit.
