My rear view mirror camera quit working I checked the fuse it's good the backup lights work.Help


Circuit/System Description
When the transmission is placed into REVERSE, a 12 volt signal is sent to the rearview camera image display module indicating that camera operation is requested. The rearview camera image display module then supplies ignition voltage and ground to the rear vision camera. The rear vision camera sends video information through the rearview camera image display module to the inside rearview mirror through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

VW A3 Viewer Request Reverse Light Switch Location A3

You can use the BACK UP SWITCH AS A POWER SOURCE. Locate the back up switch on the tranny. Tap into the wire that becomes "hot" when the tranny is in reverse. Use a multi tester Positive lead in the switch socket, negative lead to ground. The wire you want is the one that has voltage in it when tranny is in reverse, ignition switch has to be on, but DO NOT start car. Use a tap connector and run wire to camera power. Make a ground from camera to any point on the frame of the console. Put a fuse in line in the positive power wire to the camera power input. When you put the car in revese, the camera will come on.

Black screen pops up states caution your screen may seem reversed


I'm assuming this is a DVD player or at least contains a video screen. The message you are seeing sounds like the rear camera input has been activated. They give this alert to inform drivers that the view through the rear cam may be reversed. Most cameras have a switch setting to allow this adjustment.

If you do not have a rear camera installed, then it sounds to me like the rear camera trigger has been improperly connected. This is a wire that when it sees a 12-volt signal, activate the rear cam input on the radio. If you do not have a rear camera, this wire should not be connected. You did not give a make/model so I cannot begin to guess the wire color, but look for a wire that is not either black, red, yellow, white, gray, green, violet, or blue (with or without stripes). There is no standard color for this wire. Some Alpine units use orange/white, but on most radios, this is a dimmer wire. Pioneer and Kenwood often use a light purple or purple/white.

Find out what wire is for reverse camera and disconnect it.

My pioneer double din screen says ''Caution, screen image may appear reversed''...how can i solve this problem?


Hi,

As you know, you can use this DVD AV Receiver with a rear view camera. And also it can be installed to switch automatically from the video to rear view image when the gear shift of the car is moved to Reverse position.

But it is important to use a camera which outputs mirror reversed images.
Otherwise the screen image may appear reversed. And this means that you will see the rear view reversed in the monitor. And that may cause accicent and injury.

To solve this problem, first check your rear camera whether it has the capability to output mirror reversed images.

If it is, then check the wire connections of the rear camera using the operation manual or ask a technician.

Also check the settings of camera polarity if it is set properly or not in the system menu when connecting the rear view camera.

You can download the operation manual (pdf file) by clicking here.

I hope this helps.

If you would like to vote for the answer, this will help the others to see the similar problems solved and also will be a satisfaction factor for me to continue helping you.

All the best.

What does the green/white wire connect to on my jensen vm9312hd? Says it is reverse +


Rear View Camera Input: The VM9313 features a composite video input and a green/white wire lead attached to the harness for connection of a rear view camera. If a rear-view video camera is connected, the unit is on, and the TFT monitor is retracted inside the unit, the TFT monitor automatically moves into the viewing position and Camera modes is selected upon shifting into Reverse gear. When shifting into Drive gear, the TFT monitor is retracted back inside the unit. If the monitor is already in a viewing position and in display mode, the monitor automatically switches to Camera mode upon shifting into Reverse. When the reverse driving stops, the monitor returns to its original input display mode. You can choose for the monitor to display a Mirror mode image or a Normal mode image from the rear-view camera.

The rear camera have two wires: one is Video AV2 and the other is black/red color, OK. Now, my question is:Where to connect the black/red wire? Thank you.


This is the power connection.

You need to connect this to a 12v switching circuit to enable the camera to overide the current display.

For example, you could attach it to the reversing light switch in the gear box so that when you select reverse the picture is over ridden with your camera view. Or to the reversing lamp. You could connect it direct to a switch for manual control.

Rear camera to show on screen in reverse? panasonic cq-vd7001u


It sounds like you may not have it wired correctly. When the vehicle is reverse the cam works, but when you shift to any other gear IE: park, drive etc you go to black screen as if no signal. I had basically the same problem on my unit, different unit but...on the back of my unit there was a wire, you probably have the same, that said rear cam 12v dc.I assumed this meant any positive wire would do, but this is NOT the case. That wire must be hooked to the 12v positive reverse light. With my cam I had the wires from the cam hooked up, red to positive reverse light wire, black to ground and obviously video wire to the video in on the unit. but the problem arose with that rear cam 12v dc wire on the back of the unit. It NEEDS to be connected to the same 12v dc wire as the cam itself. This acts as a 'switch' when in reverse, IE: the reverse lights come on sending power to the wires to turn on the cam. When you're not in reverse the camera 'switches off' because the lights are not on, thus no power is being sent to the wires, thus returning the unit to its normal operating screen. This worked for me, hope it helps. Good Luck.

Rear view camera setting???


Dear debbie,
This could be caused by the following:
Purple/white "reverse sensor wire" not connected to vehicles reverse lamp harness. (Are your reverse lamps functioning?)
OR
Reverse cam video out not connected to Kenwood's "rear view camera input" (Yellow RCA socket behind the unit).
The monitor set up controls merely switch R-cam betwen "full, just, zoom and normal" modes. No provision here to ebnable or disable the cam.
When you put your car in reverse dos the monitor screen change?.

Panasonic ag456


these camera should operate with only the adapter, but they are notorious for having broken solder connections on the rear board where the audio and power connectors are. disassemble the camera and re-solder the connectors on the board; you may need to add a little epoxy glue to help hold the audio connectors.
