After a lot of waiting on tools (D-Link dub-e100, VCP, and some online help), I finally have a working MIB2STD in my 2015 GSW S.

But the rearview camera (RVC) is not working, the only thing not working.

Here is my long coding on 5F:


Anyone with experience in what could be going on, probably some other setting somewhere else?

If I remember, I had the issue too, and it took a couple times opening and closing the module in VCDS to get all seven of these adaptations to take:

Bill @ ATR said:

To re-enable the PDC "Park Pilot" screen and RVC overlay if not working after an MIB2 swap, open the adaptations menu in the "Information Electr." module (5F). Then make sure the following are set:

ENG122227-ENG117496-Car_Function_Adaptations_Gen2-menu_display_pdc activated

ENG122227-ENG117500-Car_Function_Adaptations_Gen2-menu_display_pdc_after_disclaimer not activated

ENG122227-ENG117497-Car_Function_Adaptations_Gen2-menu_display_pdc_clamp_15_off not activated

ENG122227-ENG117498-Car_Function_Adaptations_Gen2-menu_display_pdc_over_threshold_high activated

ENG122227-ENG117499-Car_Function_Adaptations_Gen2-menu_display_pdc_standstill not activated

I have additional retrofits on my car (2015 GSW Highline SEL) like Active Info Display, ACC, so it'll be different, but here's the coding off my 5F MIB2 to compare to yours:
02 73 02 02 00 00 00 00 01 22 00 02 00 1B 00 10 2F 01 00 F5 71 70 00 00 DE

I didn't think of the adaptations, and indeed this one "ENG122229-ENG117710-Car_Function_List_BAP_Gen2-parking_assist_0x0A" was not active. Unfortunately, changing that to "active" didn't solve the issue. The old MIB1 has it inactive too.

Also, my car doesn't have parking assist, or lane assist, so I wonder if there is other adaptations that I need to change. I tried mimicking the adaptations from the MIB1 and that didn't work either.

Long shot, but have you tried the old-timey computer fix (akin to unplug, reboot, replug): Change the coding for RVC to off, turn off the car, turn it on again, code it back on?
The binary coding is so low-level that I doubt it would make a difference, but it's something I'd try.

Your coding in Byte19 is D4 (11010100).
My coding in Byte 19 is F5 (11110101)

So, differences are I have bit2 and bit7 "on", whereas you have them "off".

Try F5 there and see what happens (?).

Nope F5 didn't solve the issue, but worth the try, thanks!

This new MIB2 came out of an Atlas, which I'm sure didn't have the same setup as my car...so frustrating, the RVC is the only think my wife cares for, not even radio (her car).

It's as if the MIB2 is not even looking for the signal, the screen does not go black, does nothing while the emblem swings and the lights come on. I thought that was a CANBUS signal, the whole of it as soon as the shifter (manual) engages reverse.

Genuine VCDS but second hand, so I never paid and register to my name

Found it!!!

From this forum post #10

5F adaptation:
IDE04307-ENG117712-Vehicle function list BAP-VPS_0x0B >not active -

Et voila, a fully functioning lowline-rvc with a 3Q0 035 844B (MIB2) out from a 2018 Atlas.

My parts list:

Main unit: going out 5G0035844 (MIB1, Panasonic), going in 3Q0035844B (MIB2, Delphi). Ebay for $125
Screen: out 5G0919605H, in 3G0919605H. Ebay for $100
USB jack: removed the MDI, routed and connected 5G0 035 222 E. Ebay for $49
D-Link DUB-E100 (the black one): Groovesland for $36.56
Online help from Brazil (only 1h difference): $80...I only recommend you go with this guy if you are pretty proficient yourself as he might not be able to get every single detail (adaptations) completed.

I did buy VCP, but you don't need it if you already have VCDS. No need for VAS tool or ODIS with this Brazilian guy.

Total $390.56, I say I did not too shabby.

Super glad you got it all figured out!

Though, I’m super curious how the Brazilian guy was able to do everything without any sort of interface to your car?

He used just the USB connection to the MIB2 (via the D-Link DUB-E100), my laptop with TeamViewer, and an SD card which I had to switch back and forth between the laptop and the MIB2.

He did the long coding of 5F and most of the adaptations using my VCDS under TeamViewer.

I do have to say that the Component Protection fault remains, I can see it using VCDS in both the Gateway and the MIB2 unit, but the fault doesn't impede function at all.

Also, there was at least another adaptation needed to get rid of fault 1555 Check Software Version Management. I recommend downloading XaGiCo guide, the fix is there plus much much more...all you have to do is calculate the new value for this adaptation IDE02502-Confirmation of installation change in 5F

1. Use this website http://xor.pw/
2. Add current adaptation value in First Input I INPUT (hex b16)
3. Add value 51666 in Second Input II INPUT (dec b10)
4. Click Calculate XOR
5. Add the result as new value for the adaptation channel (hex b16)
6. Clear errors

Some more info for whomever wants to do this retrofit:

I don't know all the whimsical names: composition media, composition colour, discovery, discovery pro; I wanted basically the same I had but faster, gaining USB, and Android Auto, no maps, and my car has no Fender amplifier, rain sensing, park assist, nor lane assist, only KESSY. You need to be aware (I wasn't), that even if you don't have those, the car the new infotainment is coming from might, and you'll need to select those out, or you'll have issues like my rearview camera not talking to the infotainment (or vice versa).

Part of the coding for those options is in the long coding of the infotainment channel (5F), an even bigger part is inside the Adaptations. Luckily you can save both and compare between the old parts (coding and adaptations) and the new parts.

This thread is super useful, but extremely lengthy: https://www.golfmk7.com/forums/inde...o-mib2-infotainment-conversion-part-1.343701/

Tips and tricks:
  • The higher the letter of your part number, the newer it is 3Q0035844 B is what I procured, for example
  • Save the long coding and adaptations. XaGiCo's guide has the method to save everything using VCDS, VCP, ODIS, or OBDEleven
  • DO NOT turn the car's ignition before you test everything out, you'll be tempted...DON'T! The moment the ignition is switched, the CAN Gateway and the new MIB2 communicate, which triggers Component Protection
  • Once set, Component Protection will be on, even if you disconnect the car's battery, and/or hard reset the MIB2, CP creates a permanent memory that this new part does not belong in this car
  • Do all your testing (maybe you get a bad part) without turning the ignition, you'll be able to test almost everything without flipping the ignition, make sure your new USB jack works, audio works, MIB2 is not stuck in a reboot loop, or blue screen
