Hooked up the system, there is voltage at both connectors, with the vehicle in reverse, the monitor is not on

You have to make sure you are connected to the reverse light circuit. Also check the polarities maybe.

Some highly fuel efficient vehicles use PWM type power which is a pulsed 12VDC and not sufficient to power a camera or a screen. Hot wire for full time on or purchase a PWM relay. I have not been able to locate one. Please advise when such is located.

What I found was that the power connector (cigarette lighter adapter) needed to be spliced into the power connector before it would work. The wiring diagram leaves a lot to be desired.

That's normal it is reading the alt ouput of the the vehicle when it is running. when the vehicle is not running it should be a steady voltage reading.

Yes, you could have ground and power reversed. Simply reverse the existing wires. If it used to work and now will not, you may have accumulated dirt/bugs/etc in the valve that is stopping the process from working. Time to take apart, carefully noting the sequence, and clean it up.

Kathy,Turn off the engine. Wait 15 seconds, turn the engine back on. Check to see if the Green and Red lights on the unit are on. If not push the middle button until you hear the computerized voice say "Language". If that does not do it, something has come diconnected from the power source. Check the in line fuse and then the power conncetion to the battery.

Check the voltage on the cables by using a voltage Meter when you turn it on.

It's power by the vehicles 12 V system, its powered up when the vehicle Is started and down when the vehicle shuts off

I wondered the same thing. Instructions are LAME and then some. The key is connect the Green wire to backup lights positive which has no power until you put vehicle into reverse. Green wire is the control. When you shift into reverse, power is sent to green wire to monitor and it turns on. When not in reverse, monitor is just OFF, no blue screen, just off. Also make sure camera ground back there is to the body metal ground and nothing else if you have a newer vehicles like 2012 sprinter van, computer did not like camera ground to license plate light wire neg, would disable camera somehow.

The screen is just dark with no input signal. If your backup camera is wired to your reverse gear lights then the monitor will only show a picture when the car is in reverse gear.

Turn your wires around rewire it up. make sure it's grounded right on both sides

You might check the forward / reverse switch and or the off / on switch to ensure the are connecting properly.

The front half of the kit incl the monitor is mostly permanently wired and is on. The rear kit is wired to the + 12V at the wire going to backup(reversing) lights. To be always on, the rear kit has to take the 12V supply from the front probably from the Accessories posn of thein switch.

The base unit had indicator lights showing when it is and isn't charging. As well as power and mode

Ckeck if it is correct power and Voltage. May be the BMW computer is checking the load current and found out of range due to diferente rating.

First check that the system has power getting to it. It needs 12volts , check for bad fuses also. Check to make sure the cable connections are secure. Then check cable for damage..breaks,freyed wires etc. The trouble with my back up system was not the camera, it was a bad grey video box the camera plugs into. I found this out because the camera would work when I would wiggle the wires at the grey video box.

are you sure you connected the lead to the back up lights so it would know when you went into reverse? You could also try to reverse the inputs.

Have you swapped the wires on the other monitor and the other one works? Then its the monitor itself. If the one that was working doesn't work, then you have a bad connection.

There is a supplied cigarette lighter power cord for the head unit and the sensors require a 12 volt power supply and a connection to the reverse light wiring. Thanks, Jerry
