HOW TO CONNECT eBay BACKUP CAMERA TO NAVI

[TerminatorX5]

is your camera "plug-n-play" for the license plate light opening? Or, you need to modify something?

Ok, SUPER close now, I wired it up to the relay as advised and the cam switches properly when put into reverse.
Now it's flickering madly when the engine is on and slowly flickering when the engine is off but in reverse with accessories on.
Any advice?

Re-reading, when I say as advised I mean as per the picture of the relay with the wires labelled that's earlier in the thread.
This may be wrong in reading post 80 by Ty.

reverse lights are not plain 12 VDC applied to the bulbs, it is a Pulse Modulated Wave, that is coming from the LCM in order to mionitor the status of the light bulbs - as a result, the pulsed voltage applied via relay will flicker the screen.

Do you have a factory PDC installed in your car?

Stoopid work getting in theway of my DIY.

here's a pic of the cam, I am hoping to have it fully installed this weekend too.

yes front and rear

hmmm....SO does your post above mean I've got the pulsed 12v from the reverse lights instead of a steady 12v from somewhere else?

Doesn't matter, it's not there to give you a steady 12V, you don't need a steady 12V. It's there to trigger the Relay so the Relay can trigger the TV to switch into reverse mode.

It make more sense to use the PCD wiring to wire up your reverse cam if you have the time.

the PDC module is located under the spare tire in the battery compartment, next to the BM radio, and it has 3 plugs. The middle plug has multiple pins, and the Pin #7 supplies signal voltage to the green light in the front of the car in the button module in the center console. When PDC is engaged, the green light on the PDC button lights up via Pin #7 on the middle plug - the voltage and amperage are very low, and that pin supplies (+) voltage.

If you will take that (+) signal and convert it via a low voltage/low amperage relay to a (-) ground, and apply that (-) signal to the wire for the reverse signal, you will have the reverse camera engaging everytime when the PDC is engaged. It also will give you an ability to activate the camera by pressing the PDC button on the center console switch panel (module A169).

there is a drawing of that connection somewhere on this forum, rather easy to accomplish if you have a factory PDC - only one tap to pin 7, one relay and reliable ground.
So, if you tap into Pin #7 on the middle plug on the PDC module, apply that signal to a coil of a relay, and have relay contact apply ground to the reverse camera wire off the TV module, you are done...

Cool, I'll give it a try, thanks

do you have a picture of your actual camera?
