This unit is actually located in the roof, and is directly attached to the shark fin antenna. Which means it is a modest PITA to get to as it would most likely require taking down the roof headliner. The TCB is module A231.

I can confirm the card is in the roof antenna. I had issues with connectivity and dealer exchanged my cell module and they had to remove headliner and get to the fin like cover from inside. Of course they did not registered the new card with ATT so I had to go again and have them fix the issue.

Thank you, I genuinely thought it's in the head unit like I saw in the video. At least now I know for sure where it is.
