VW Reverse Camera and RNS 510

Good day.

I installed a VW RNS 510 infotainment system in a US-spec Jeep for a friend.
I simulate the necessary signals and transmit them to the RNS via CAN.
It works perfectly fine.
Now, one of them wants to connect a reverse camera.
So, I have programmed the RNS 510 accordingly.

Okay, here's the translation:

'Now, my question: What signal is the RNS 'listening' for in order to enter RFK mode?'
I'm going crazy. I've tried pretty much everything, but nothing seems to work.
I personally own a Golf 6 with a 'RFK Low' system, so I can constantly log data from it.
And now for the curious part: I've essentially 'cut' all the CAN messages in the Golf 6 that transmit the information 'reverse gear is engaged,' but the system continues to function normally.

Does anyone have any information about that?
I would also be grateful.

Is there any RW Gang information that I might have missed?
I was already thinking about BAP communication between the BCM and RNS, but that can't be the case, since the Golf 5 also has an RNS, but it doesn't have BAP communication.


Greetings to you all...

Hello, sorry for writing in English.
First, access the hidden menu in the RNS system and select "CAN". You will then see an entry labeled "CAN Reversing". Now you can experiment with that.
I suggest trying the following IDs:

0x351, len: 8, period: 200ms, data: 0x02 xx xx xx xx xx xx xx xx
0x470, length: 5, period: 100ms, data: 0x20 xx xx xx xx
0x531, length: 4, period: 100ms, data: 0x20 xx xx xx

Hi and thank you for your reply.

Well... that's what I did first.
The RNS displays 'CAN reversing' when I shift into reverse.
But it won't display the Camara image.

I have now emulated the entire CAN bus functionality of a Golf 6, but the camera images are still not displaying.

And 'yes', the RNS is coded to 'Reverse cam low installed' .

It's driving me crazy...

Everything works perfectly...
Illumination, speed signals (0x359 & 0x527), reverse gear (When driving in reverse gear, the RNS recognizes it on the map), MDI works, OPS works (Installed it from a Golf 6 with the ECU).
I installed a VW DVBT TV tuner, and guess what happens when I put the car in reverse... It shows the camera image from the AV1 tuner.
But I only want the original RGB camera, not the TV tuner.

by the way... the message 0x351 is not available in my Golf 6!?!
Maybe that is a problem...
Can you provide all 8 bytes of message 0x351?
Or is it perhaps just a copy of 0x527?

Best regards, and many thanks.

The 0x351 module in my 1Z Octavia (pre-facelift model) contains speed and reverse/forward data.
It is 8 bytes long.

Code:

Byte 0: 0x02=reverse selected, 0x00=no reverse selected, 0x01=?? Speed = (byte1*(2^+(byte2-1))/190 Bytes 3-6 = all set to 0 Byte 7 = almost always 0 / sometimes 0x80 Example: 0x351 dlc:8 data: 006A6F0000000000

Perhaps there's an issue with the "terminal 15" emulation, and the RNS (radio navigation system) doesn't know if the ignition is on?

I will try to code "camera low" on my RNS and conduct some experiments.

Cheers!

Thank you for your support...

Yesterday evening, I had the opportunity to do some logging in a 2012 Jetta.
The ID 0x351 is available there... that's strange.
'I then disconnected this ID, and the camera image no longer appeared there.'

On Saturday, I will attempt to replicate the exploit known as '0x351' in a US-made Jeep, and we'll see what happens.

Why is VW using three speed signals in the infotainment CAN?
'In the 2012 Jetta, I found the error codes 0x351, 0x359, and 0x527?!'

Thank you again for your support.
If you need anything related to VW CAN, just let me know.


By the way...

>>>> Byte 7 = almost always 0 / sometimes 0x80
'The 0x80 indicates an error in that ECU, but I don't know exactly which ECU is sending the 0x351.'
I can see that very often...
0x80 in the last byte of a message, and then it disappears after a few seconds or minutes...
When I access the ECU at this time, I can see 'Sporadischer Fehler' (Temporary error??).
When the 'Reset Counter' exceeds 255, the failure disappears again.

Have a great day...

Hello,
"Regarding 0x80, yes, I noticed that there are some messages that inform the gateway (and interested modules) about the state of a particular module. I've been calling them 'heartbeats'." They are sent periodically, with a period of less than 1 second.
Okay, I understand. Please provide the German text you would like me to translate into English.
ID 0x543 (RVC): If byte 0 equals 0x80, the gateway indicates: RVC Malfunction.
If no such message is received, then the gateway indicates: "No signal/communication."
But usually, fault information is located in the first byte of the message.

Have a creative weekend!
