Discover Media retrofit

Yes they have component protection.
If it hasn't been patched it will lock instantly if the instrument cluster supports CP, otherwise after 6 hours if cumulative runtime without being able to contact its original CP master.

Thanks, assumed so, the next question would be then .... what would be the best/easiest/cheapest way to remove said component protection?

As in, who can patch the board?

[kamold]

I can do them, or get you a patch board and instructions if you're familiar with removing and soldering eeproms and reading/writing.

Hi @kamold,
This post is really brilliant, I have used it for my discover media retrofit in my CC, CP removed from the person I bought the unit from, all activated and working properly except the camera which I need your help in it.

My highline camera was working perfectly with old RNS510, I have tried after the retrofit to use RGB converter but it gives always black screen with no signal. I tried to test it even with a TV using RGB converter but again I got no signal.
I then bought a second hand 7n0907441b module to get rid of al the cables & converters. connected all wires as supposed to but again I receive no signal in the MIB. Module is read by VCDS but cannot be coded "error coding rejected"!!

6c module is giving two failts (video line no signal & databus)
After googling many forums and posts I have done the below:
Enable and testing VPS but still nothing is comng to the screen at all even the OPS disappeared.
When enabling the low RVC in 5F module it pops up a black screen for 3 seconds and then shows "the parkpilot is currently not available" then OPS only can be activated until the next reboot of the MIB so I assume I have a coding problem for 5F module somewhere and I guess my camera might have diffictivness somewhere. What do you think?

[kamold]

Rvc module has no video signal as the fault says.
Check your wiring per the wiring diagrams.
Post your coding string to check it is correctly coded.

[kamold]

Also check 5f coding and ensure rvc low bit is enabled in byte 19 I think from memory.

Thanks a lot Kamold for your prompt response.

My code for camera module is:
01730001C301000300

And yes RVC low in 5F module is active.

I take it that the camera is a flip badge type?
If so is it actually opening when you put the car in reverse?
What is the actual fault codes from the RVC?
Is it automatic or manual car?
What software version is the RVC?
What car did it come from (ie what parameter set is loaded on the camera)?

[malsageer]

yes the camera is the flip badge type and yes it is opening once reverse without any error.

my car is 4 motion full automatic with VR6 engine.
the fault from 6C control module is below with software version and it came from CC as per the seller from eBay:

Thanks a lot for your time and assistance

The first 2 bytes of your coding are not documented in VCDS.
But my coding is:
01130608A201000700

Note I am RHD, don't have a flip badge camera or trailer.
I would try changing just your first 2 bytes to 0164 (passat CC) and see if that makes any difference.
But otherwise it looks like the video input to the RVC module is not correct.
