Hi guys, I just bought a pioneer rear camera for my Z3 and the only wiring I see is a brown single RCA alone with a red and black cable. Do I need to install an additional cable for my reverse? Does anyone has a DIY instruction.
The reverse signal is on the wiring harness for your Z3
Violet/white (REVERSEGEAR SIGNAL INPUT)
This is connected so that the navigation system
can detect whether the vehicle is moving
forwards or backwards. Connect the violet/white
lead to the lead whose voltage changes when
the shift lever is put in reverse. Unless
connected, the sensor may not detect your
vehicle traveling forward/backward properly,
and thus the position of your vehicle detected by
the sensor may be misaligned from the actual
position.
The red and black wires are to power the camera itself. Connect black to ground and the red to either Accessory switched +12V or to the +12 power at the reverse lamp so it only turns on in reverse. The brown wire goes to the RCA input on the Z3 (also brown) The Violet/White wire as stated above automatically switches the Z3 to rear view camera mode when it receives a signal (when you put it in reverse.)
Thanks for the info, however my Z3 is already installed with nav and working properly. I'm just addinginto the system the pioneer rear camera and inside the box the only wire hardness it has it's only the red, black and the brown single RCA, so that should work right?

I understood your first post completely and provided the instructions that i did with a purpose.
Yes it will work, but if you want the camera to turn on automatically you MUST connect the Violet/White wire from the Z3 to any wire in your vehicle that changes to 12+ or to ground when your vehicle goes in reverse. That wire signals your Z3 to go into "rear view camera mode" so you don't have to fiddle with a bunch of buttons every time you put the car into reverse.
You will be able to tell if your Violet/White wire is already hooked up if the screen goes black (prior to camera install) every time you go into reverse.
