AppConnect USB socket information for Apple Carplay

[alaskan]

Hi everyone, after (unfortunately) being quoted around 300-350€ for AppConnect activation (via dealer), I wanted to take a look at the USB socket that also likely needed changing to be compatible with Carplay (Apple), because only one of the dealers I asked confirmed that this will need changing too.

I was able to pull out my USB socket without taking apart the entire center console (fortunately) and found out I have the "6C0035726C" socket, which I understand supports AppConnect and Android Auto, but does not support Apple Carplay. It is purple and has the main cable + 2pins on the side.

Now based on the info from viewtopic.php?t=74656, I now need a "6C0035249B" socket that supports Iphones. My headunit is 3Q0035824B, SW version H28.28.133_STD2Plus_EU, 6C 2017.

After searching, I'm not entirely sure of a few things and wanted to clarify:

1. Let's say I get my hands on a "6C0035249B" with the extra 2 pins - is the install straightforward, i.e. unplug the old socket and plug in the new one? Looking at the pictures I found online when comparing those two sockets, It seems that the new one would be physically able to be connected (see screenshot below).

2. In case a whole new cable/harness is needed as well, how difficult is to install it to the headunit? (I'm almost certain that in that case I'll need to take the whole center console off ) I was thinking of attaching the new cable to the old one and just fishing it out from the side of the headunit via glovebox...

3. After the install the coding seems straightforward - Module: 5F and proceeding according to this video https://www.youtube.com/watch?v=JH6wFeh8SmQ. Is this procedure different for different headunits?

4. I found supposedly two types of 6C0035249B, one having the extra 2 pins and one without (see links below). Is this just an error in the listing or are there really two types? Can they be differentiated somehow when ordering online?

Thanks!

Sorry if this gets your hopes up, though I was looking into doing the same thing and it seems you have all the answers already mostly.

I figure you can't just ask the seller of these what the difference is? I see there is a price difference which implies one may do more, especially if that is the one with extra pins.

I managed to order a new "6C0035249B" socket (green, HSD 4 pin + 2 pins on the side), just based on the pictures from the item listing, did not check with the seller.
Since the 2 extra pins supply 5V power to the USB port, and I currently do have those 2 pins, it made sense to order the same thing.

Some detective work followed - I checked pinoutguide.com and this HSD infosheet - https://www.delock.com/infothek/FAKRA_H ... hsd_e.html to confirm whether I need to do anything else or if this new socket is just a plug'n'play.
Good news is, the HSD 4 pin pinout for the socket should be the same (unless one is using a knockoff cable), the bad news is that based on the color of the HSD connector (e.g. green vs. violet), the little plastic tabs inside the connector are different (see the Delock HSD web above) which prevents using differently color-coded male and female connectors together, as was further confirmed by this video by mr fix: https://youtu.be/7yTYaxzeXfY?t=163

Luckily it seems that it can be solved by just simply shaving off one of the plastic bits that are in the way.

I plan to test it this week and should that work, book an appointment at the stealership for the appconnect activation code release, and code 5F myself afterwards to support iphones.
