Ok, JHP sells a video connector for the IQ unit.
The connector is on the pricey side (Over $100 with shipping), but at the moment its the only option out there (Unfortunately).
The video connector includes 2 RCA connectors, 1 for Reverse Cam, the other for RSE.
There is also a second connector for RSE Audio input, which replaces one of the connectors on the Main IQ quadlock connector.
As for connecting it all up, this connector makes it very simple, and its just a matter of connecting power to the camera (From the reverse lights), and connecting the cameras Video RCA connector to the above connector.
(And also enabling the Reverse Camera on the headunit).
