Hi David I have the Blaupunkt New York 830/835 fitted in my van it uses the double din opening on the dash.
John.
Similarly my van has a double din radio unit added, which has the option of an external video feed from a reversing camera. I'd like to add a hard-wired combined brake light camera but sadly it doesn't look like there is any pre wiring. I'm not sure how feasible it will be to install cabling from front to back past all of the furniture.
