Option JH6 for missing Hermes module?

On my window sticker from my 2021 Cargo, I have an option item "JH6 Pre-fitting Communication Module (LTE) for Dig Services" with a $-183 credit. I'm guessing that this is a credit for the Hermes module for telematics that was not available at the time the van was made. Under my steering wheel I have found the wiring harness and connectors for where this communication module is to go. Has anyone here been able to get their hands on this module and successfully install in their van with the prewiring JH6? I'm looking to be able to remotely lock/unlock the van using the mercedes smartphone app.

Also, if anyone here has a van with option JH3 (Hermes module actually fitted to the vehicle...), have you got the capability to remotely lock/unlock the van using the Mercedes app? If you do have the module and this capability, would you mind taking a photo of the white sticker (with all of the data) on your Hermes module for me? It is located either under the steering column under the dash, or behind the 2 cupholders in the center of the dash. That cupholder pulls up and out pretty easily without tools... Here's a photo of what the Hermes module looks like. It's about the size of a pack of cards...:

Many Thanks!

Not a problem. And I have to correct myself. Last October (21), we paid $308.16 to VZC*MERCEDES MBRACE GA in order to be able use the Mercedes app and remote start and pre-heat our GLE she uses in winter. This was as the vehicle went off warranty and the free service years expired. A purchaser of a new MB gets free Mercedes me for a few years (same as warranty?) and then it is a paid service ...

Of course I wish it was just a key fob thing without cellular and fees.

Things change, rebrand, ...

I have a 2021 Getaway and use Mercedes Me Connect without a paid subscription. I did have to remind the dealership concierge to register that feature for my VIN. It was my understanding that was free for the first 5 years. I read that on my dealer's website. Of course that won't help because that can't work without the currently unavailable LTE module. (Edit: which mine had --I just noticed that icerabbit was ahead of me by a few seconds)

No Joy. There was nothing under there that I could get close enough to identify. I did glimpse a couple of modules --one big one squarely mounted to the floor under what you can see in the picture and another candidate under the dash --well to the right of the steering column.

The weather in my driveway is awful tomorrow, but I will try to dig out my bore scope and take a closer look next week.

No Joy. The module under the cup holder on the floor was the air bag controller. The other candidate that I thought I spotted ended up being a part # sticker on an unrelated not-a-module part. Even with a USB bore scope, I didn't find much else.

Your next best bet may be to go to the parts counter at a dealership and ask them to lookup the part number. As much as I love solving a mystery, this one was beyond me. Good luck.
