Questions about the navigating SD card

[LYKKEGUTT]

My car is Model S 2013. I have a question about the navigating SD card. I plan to replace this navigation SD card.
On MCU1. How many gigabytes SD card can it support ? 16G or 32G or 64G or 128G ?
Thanks a lot for your answer !

32G

Can only support up to 32G ?

That is my understanding for the early cars. They originally had a 16GB Class 4 SD card installed. This was 8 - 9 years ago, a long time in technology. Doubling the memory should do nicely, and getting a fast endurance SD card should speed things up. The MCU1 may not be able to address more than 32GB, and I doubt if it needs more than that. I can't find where I found the 32GB, but I know others have installed this much successfully. More really isn't going to help that MCU. It is too slow, in my opinion.
