BMW E38 Rear View Camera installation
I got the relay switching from bimmernav.com
Same as the one you got in the pictures.
Installed everything as describe:
87= Yellow (connected to ground chassis)
85=Red (connected to ground chassis)
30= Blue (to blue connector pin #17 video module)
86=White (to reverse 12+ wire in the tail light)
The RCA cable to the pins #13 (power input) and #14 (ground input) of the white plug (video module)
However when I put the car in reverse the screen turns black; like if the camera was not connected, but I check the camera with my camera security tester and it is video coming through.
And then when I plug and unplug the connector from the TV video module it works one time and them does not work.
Any ideas what could be the reason?
