Rear Camera Not Working - Interior/Exterior/Lights/Glass/Alarms/ICE/HVAC/Other - The Lotus Forums Jump to content

Hi

I have a Launch Edition Evora fitted with the Alpine INE W925R and I think it should have a reversing camera, however when I put it in reverse nothing happens on the screen. What I mean by that is that whatever is on the screen just remains there, not even a flicker or a change to a blank screen. I can see the camera in the bumper and what I think is the wiring running around the boot. Its almost as if it is not connected though.

The parking sensors work fine.

Any ideas of what to check for please?

Thanks, Robin.

There have been a few reports of the camera not working after a few years but the radio unit should at least change to the rear camera input and just display a blank screen.

Check the settings on the radio unit to see if the rear camera input is enabled?  If thats all good and the unit is not switching to the camera input then I guess the radio is not receiving the reverse signal.  I would pull the radio unit out and get a multi meter on the reverse signal input and check that is active.  I don't have a wiring diagram for the radio but if you search there are definitely old posts where people have labeled the input pins to the radio.

When I had the headunit in mine upgraded from the original Alpine 505 to the newer 920 model, the camera also had to be replaced as the original one was incompatible with the new unit. 

I can't remember the exact details but I seem to remember mention being made that they had different operating voltages and that some wiring changes were also needed to get everything to work.

Just a thought - are your reversing lights working okay? That circuit is used to power up the camera and control unit...

When I bought my LE, the camera wasn’t working but the screen would change to black when reverse was selected. It was the camera that had failed and everything from the control unit to the HU was okay, so I’m with Jairaj on this one. It sounds like it could be a setup or plug problem To me.

I don't think the 925R is the original launch edition HU so someone has upgraded it at some time. It may not have been connected properly.

 

You can test the camera manually without having to have the reversing feed connected.  Check your manual for camera set up, instructions are there.

Thanks for your replies.

Paul, you were spot on    "I don't think the 925R is the original launch edition HU so someone has upgraded it at some time. It may not have been connected properly."

I have had chance to look at it this afternoon and, yes it looks like a retro fit and for whatever reason they could not/did not fit the reversing camera. I want to get it working so this leaves me a few questions I hope you can point me in the right direction with.

Firstly, is there a wiring diagram somewhere, so I can identify whats supposed to go where?

What do the camera connectors look like? is it these?, they were not connected to anything.

Whatever connection I need to make will have to connect up with the socket below - can anybody recommend a good place for adapters please?

Does anybody know what this red plug is for? it was not connected to anything?

I also had these 2 loose cables that were not connected to anything! Are they part of the Lotus loom? - One of them has a sleeve on it that says "camera in"

Sorry for all the questions - it looks like spaghetti behind the head unit !!

It looks like one is the mic for the hands free, one is a DAB antenna connector, and possibly, the final one is the Alpine imprint plug. Not sure about the last one though.

You'd need to check with the seller that this is camera in and not just camera out, but

Re the Lotus side wiring diagram there should be something in the service notes, found on line.

just looked up the Lotus Evora S circuit diag. Apparently fuse 18 supplies a g and n coloured wire to the hu from the reverse gear switch. I assume g and n are green and brown.

Thanks for all your help. I will look into this again at the weekend and let you know how I get on.

These forums are great 😊

Following on from my earlier post, I think the red phono is one of the sub connector cables.  It looks like the 2 loose cables are the ones from the original HU (I have the same ones in a box from when I changed mine) and I think you have a couple of plugs missing.  If you have a look at https://www.alpine.co.uk/fileadmin/user_upload/manuals//car_audio_manuals/INE-W925R/QRG_INE-W925R_EN.pdf page 14, hopefully it will help.

I changed my HU to a Kenwood and so I had to graft the old Lotus loom link cable to the one for the new unit but I assume you have the link cable and just need the additional plugs. As Paul said above, you seem to be able to get these on eBay at the moment.

Hi.

It took a while, but I got hold of a Alpine link cable for the camera input, and I thought I would try and fit it this afternoon. The problem I have is that I don't know what the (Lotus) camera plug looks like, so I am not sure what to start connecting up. There are quite a few redundant cables in there which is adding to the confusion for me. 

If anybody could post up a picture of the rear camera plug from the Lotus side that would be great.

 

Thanks 

Robin.

On mine the camera plug was a composite video RCA, so looked like the male part that would fit onto the yellow plug on the redundant part of the loom further up the thread. If you look up composite video rca it should point you in the right direction.

Hope this helps.

Thanks Steve. I think its the yellow RCA plug on the left in this picture?

Can anybody confirm please?

There were quite a few redundant cables in there which made it a little overwhelming to look at, so I have tidied it up and put all the redundant stuff out of the way.  Its easier to see whats what now.

The yellow RCA plug is currently connected to the video input terminal on the loom that handles the speaker and video inputs and outputs. I think if I connect that to the Camera 2 input of my new camera/W Remote loom that should work? 

Below is the camera/remote loom. It has loads of other cables such as speed sensor, steering remote, remote in/remote out etc... I assume none of these are needed. Any thoughts on that please?

Hi Robin,

I think you’re right with the yellow RCA plug, check online with the manual for your HU to make sure it’s input 2 though.

I think there’s also a speed input on yellow in the loom but I don’t think you need the remotes unless you’re planning to install one.

I’d recommend plugging in and powering up before sliding it in to make sure you’ve got it all working but suggest you put masking tape around the aperture before doing so to protect the leather.

I connected it all up today and the rear camera didn't work ☹️ It could be the camera is dead, but I don't know how to test for that.

Its probably a really simple fix, but I have decided to get a professional to look at it. Apart from the camera not working the wiring behind the unit could do with a tidy up and I would not be confident in making a good job of that.

Whats next on the list....!!!

Have you got an old video camera or a DVD player that has an rca input? If so, you could see if the camera works by plugging it into there and selecting reverse with the ignition on.

I managed to get a new old stock camera on eBay  to replace the one that had died on my car but replacing it was a pain.

I would personally go to car audio specialist and get it looked at ? You might end up like I did getting new head unit (apple play) which had new camera and now works fab 

the rest my son sorted out and that took several hours but saved me a few hundred in process

anoying I know but getting it sorted at car audio garage best option ?

I don’t think it’s too difficult to do as a DIY - there have been a few threads in HU changes which cover the loom splice which would need to be done as it looks like the original car loom-HU loom was left in situ and new HU wiring connected in parallel which has added to the confusion.

I changed my HU to a Kenwood with CarPlay and Android mirroring and can recommend the functionality...

Good luck and I hope you get it sorted out.

If you have a RCA connection for your camera then pop onto ebay / amazon and get a cheep replacement camera, even if its just to see if the loom is correct and its just a dud camera.  I have a cheap and cheerful camera and monitor set up for my van and the quality is comparable to the Alpine camera.  They will be a different fitting to the Alpine camera so you may have to bodge up a bracket or something for it.  But they cost £10 so even if its just to check the loom and rule out a dodgy camera its worth it.
