I was going through this list and either I don't have this RVC or I missed it. I'm going to see it again.

 

[JohnS4]

It’s an option in the gateway installation list. It will be there.
Do you have any module incorrectly coded errors?

 

[dativus]

@JohnS4
It's on the list - 6C - Back-up Cam .

I also coded for Avant because my car is also Avant and APS+

Unfortunately, nothing changes except the speakers. There is no PDC visualization and a black screen after engaging reverse gear?

I have such errors in the module. I will add that I won't have the reversing camera until this afternoon. I wanted to check if the PDC will work after connecting the module and if I put the reverse gear in, a black screen will appear (no reversing camera). This first error is not important for now - calibration.
The PDC still does not work and only the PDC loudspeakers can hear the latter.
There is no black screen when you put the car in reverse gear.

 

[JohnS4]

As you changed the coding try a forced MMI reboot.

 

[JohnS4]

Perhaps it is best to wait until you have the camera fitted, then continue your testing.
You mention that your MMI 3G+ is also retrofitted. Did the APS plus display correctly on the MMI before you fitted the rear camera module?

 

[DrGER]

Our NAR '14 A4Q 6MT sedan had PR-7T6 Navigation system (MID) and PR-7X7 Park distance control in rear with rear view camera system; the MMI3GP screenshot captured this with reverse gear selected:

The processed video from J772 was overlayed on the output signal from J794 to the display unit, so it wasn't captured in the screenshot. But I would expect that you should see the other elements of the RVC screen with RVC configured in the MMI and reverse gear selected; alas, I don't have a screenshot of the RVC "Settings" screen in my MMI3GP screenshot PNG collection.

BTW, use a CODE block to preserve the white-space of our VCDS log output pasted into a forum post. --g

 

[dativus]

My reversing camera didn't arrive today and I had to leave urgently. As soon as I get back and install the reversing camera, I will write about it

 

[DrGER]

Looking through my collection of screenshots going back to 2018, I found these settings for the "Parking aid" function:

I suspect "Display" set to "On" gives us the RVC screen, above, when reverse gear is selected (and the ignition is ON). --g

 

[dativus]

@DrGER
@JohnS4
I connected the reversing camera but it doesn't work yet. only 1 error pops up:
I didn't save the error on the computer (I forgot) but it's about calibration. I'll post a photo. As for the menu, I have it as in your photo above. The module coding is: 1020007 (7 Avant). At geteway 6C the reception was positive.
Perhaps something in the green menu conflicts with something else?
Is there RVC setting in the green menu?

edit: I forgot to delete the errors

 

[JohnS4]

Try a full MMI reset.

 

[dativus]

Try a full MMI reset.

after each change I do a full MMI restart

I'll go to the car soon, read it and maybe delete these errors.

I’m in that thread too!

 

[dativus]

I have exactly coded as in both descriptions:

and in my car sometimes there is 1 error, sometimes 2 errors :

[JohnS4]

Calibration error will remain until you complete a calibration process.
open circuit is because you had the RVC camera unplugged. You can clear that and it should not come back.
Where did you pick up power and where did you tap the CAN bus?

 

[JohnS4]

What happens if you press the parking aid button?

 

[dativus]

power supply to the thick red cable on the rear right side. I connected 2 cables: orange / green to pin 19 and orange / brown to pin 20 of the T32c cube in the comfort module (BCM2).
When I press the button, I only hear sounds from the PDC or reversing camera.

 

[DrGER]

@dativus -- You should consider adding a new Terminal 30 circuit to ST5 (top fuse panel shown in post #5), position 6 to power the backup cam control module J772 with a 5A fuse:

Also, confirm coding in the MMI main unit J794, Address 5F, Byte 7, bits 0 & 1 set: MMI 3G+ J794 Coding and Adaptations --g

 

[JohnS4]

I would strongly recommend adding a fused supply to the RVC as mentioned by @DrGER. Id also use the factory location (and 5A rating) for the fuse.

You have the same RVC module as me, (APS+/ Avant) and the coding is the same so that should be ok.

Where did you connect the video signal from the RVC to the MMI? You did not mention this yet. The wires from the RVC should go to pins 11 and 5 in the quad lock, not the spare fakra connector on the back of the MMI, this is for the TV tuner input.

There are 3 fakra connectors on the RVC, brown, green and grey. Brown is not used, green is the feed to the MMI, grey is from the camera. Check these are correct.

Lets also check the multi plug into the RVC as you purchased a harness from the web (some are not pinned correctly!)

39 - Orange/Brown - CAN LOW
40 - Orange/Green - CAN HI

43 - Blue/Red - module +ve
44 - Brown - module -ve

47 - Brown/Blue - camera -ve
48 - Red/Blue - camera +ve

The CAN connection should be done in the CAN disconnector. This is shown in the Kufatec instructions in the right hand end of the dashboard, on a facelift this CAN connector has moved to the bottom of the A pillar (next to the pedals if RHD). CAN H and CAN L should be on PIN 19. PINS 14 to 23 are the convenience bus, so any of these is OK. 13 to 9 is another bus and won't work. 8 to 1 is yet another bus, also won't work
