Reversing camera problem

Des, What brand/model?

Hi there. If it is a true reversing camera and not a rear vision camera, then it should be wired so that it only comes on in reverse!! It sounds to me that the camera is correctly wired to be supplied with power only when in reverse, but the screen unit is wired either to ignition or access, and comes on in Park mode. If so, then yes perhaps an autoelec can fix it. But if there's an intermittent fault in the unit, then it may be beyond him.
Some remote control allow the user to switch between 'rear view' and 'reverse', and so it is possible that you have inadvertently switched the unit over so that it starts in rear vision mode, finds there is no image (because the camera is powered only in reverse), and gives you the blue screen.
Is that any help?

Des. As you have described your problem, it only works in ( R ) I has probably wired up to the Reversing lights. The one I have is "Infra Red" so I do not have the same issues as yourself.

Des,

Sounds like your problem is not really a problem at all.

Most reversing cameras have a minimum of two AV channels.
When you select reverse gear, the monitor is configured to automatically switch to the appropriate AV channel automatically.

When reverse is not engaged, it is a matter of pressing the AV channel button and the reversing camera circuit is then active permanently until either you press the AV button again, or recycle the supply power.

At least, this is how mine works. The camera is connected to AV2 and requires a manual button press to select it when required. The reversing circuit activation is obviously configured to select AV2 automatically when activated.

If you have a second camera connected (eg from a caravan camera, etc.) this will use the second AV Channel.
The AV channel button usually cycles thus.
First press........AV1
Second press....AV2
ETC.

Thanks to everyone for replies.

It wasn't a problem with the settings (tried everything).

Couldn't get help from the original installer - I only have his mobile and not surprisingly getting no joy there.

So in frustration I took it to AudioFX today - they install a lot of original equipment on new cars, as well as aftermarket. They told me that when they first started installing reversing cameras some years ago they used to wire them through the ignition, as mine is, but they found that this meant that the monitor was constantly being reset. So now they wire reversing camera systems direct from the battery. The monitor is in sleep mode most of the time, and then only draws a tiny amount of power.

AudioFX have determined that my monitor is now faulty. They think that the fault was caused by constant resetting when the car is started. They have rewired and installed a new monitor - total cost $250 (ouch). (Kept the original camera which is good quality and works well.)

Hope this is a cautionary tale for everyone thinking of getting a system installed.

Cheers,
Des
