problem installing back up camera system
 

I am trying to install a back up camera system on a 2004 X5. The system works with the key on number 2 position but does not work when the eng in me is running? The Camera mounted on the upper rear panel is c ok none Ted to the how wire of the reverse lights and ground. The monitor is connected Ted via RCA cable from the camera and has a direct 12 v ok it connected to in and a dedicated ground! Any help would be appreciated as this is very fustrating trying to get it working!

Alright mate,

I had the same problem with mine when I fitted it. I set mine up with a standard 4 pin relay powering the camera.

Pins as follows

85 - Chassis Ground I just found the nearest bolt and used a simple half circle crimp connector.
86 - Reverse light Wire Tap, (used as a relay trigger)
30 - 12v Power. Now this one you need to find a fuse that is live when the ignition is on or a constant 12v (I used a multimeter to find one then used a piggy back fuse on to my trailer hitch fuse)
87 - power wire to your camera.


The issue you are having is that the lights on these BMWs is supplied a steady 12v when the engine is off.... but then when it’s running it “pulses” the voltage to check that the bulbs haven’t blown (correct me if I’m wrong). But basicly you don’t get a steady 12v so the camera won’t turn on.

Fit the relay and it should work sweet

Thank you I installed the relay and I am operational! Appreciate the help and advice!
