HOW TO CONNECT eBay BACKUP CAMERA TO NAVI

[TerminatorX5]

pw, i suspect that this particular camera will not fit into the license plate opening... before wasting your weekend, pop the license plate light cover and see if it will or not... if it fits, I want to see the pictures... If it doesn't fit, then... maybe a bumble bee camera?

there are schematics of the connections from the camera to the TV module and the trigger wire in this thread - camera needs power, the video feed from camera goes to TV module, and the trigger wire needs ground to send the video signal to the front of the car. you should not use the reverse light circuitry as the voltage there is NOT steady 12V but rather a pulse modulated wave, which will result in front image flickering. Since you have the factory PDC, you may consider using the Pin 7 from the center plug of the PDC to get a (+) signal to a SMALLER relay (see this very thread for the part number and the specs), which will apply (-) to the trigger wire.

One thing at a time... check the camera fitment first... then post your progress, we will guide you further...

TerminarorX5,
thx for your hint.
The camera does not fit, not because of it's size, but because the inside of the trim which holds the opening button and the license plate lights are a unique piece, with a circuit board inside, so, it's not possible to remove the bulb holder, only the transparent plastic window, which i discover, has part of the tabs broken.
So, i'm considering the following:
Getting the other camera i have (Car Rear View Reverse Camera for BMW 1 3 5 6 7 Series x3 x5 x6 All BMW | eBay), cutting the cable from the camera to the splitter, make it fit to the lights and push button connector, make mini three pin connector and connect it to the splitter, which will be inside the rear door. As these cable is not shielded, i think it will not pose a problem. After done, i will pots the pictures, so to go further.
Best regards and thx again for the hint. Spared me time
Paulo

video feed from camera goes to tv module - yellow cable from camera (signal and ground) - signal to pin 13 white connector and ground to pin 14 white connector - white connector of video module.

small relay - 12v low current coil - coil to pin 7 pdc and ground.

relay feeds ground to pin 17 of blue connector from video module.

Did i get it right?


Best regards,

Paulo
