WTH is up with the hidden USB Port SIM in 2018 Yukon?

[Ct Pirate]

I bought a 128 gig micro sim and the adapter to go in the hidden port behind the screen and dumped all my files on it and doesn't work! Seems its not recognized?? SO I go out and buy a 64gig Micro Sim thinking it a capacity issue and load all my stuff on it, pop it in and voila it still doesn't work either!

I toss a old school sandisk 32gig micro card in and it works? WTH man? It's driving me nuts!!! Anyone having any luck with this issue?

May be a 32 gig Max.

Not sure but I'm going to try a couple more sims and see what the deal is. I would love to just have a 128 and load up all my stuff on it.

X2 on the @yates ™ answer.

Sounds like your host device is compatible with microSDHC (32GB) but not microSDXC (>32GB).

this is when a call to GM would clarify the issue

May try a flash drive instead. Not sure if the SD card is meant for music or not.

Hmmm yeah good idea I'll try a flash drive.

I have a 128gig thumb drive loaded with music videos and movies in one of the USB ports in the center console and it works fine. Maybe it’s the format of the micro usb or maybe it’s because you are using it with an adapter. I can’t see the CUE system using being able to use a larger thumb drive than the Mylinc

I just stuck a 128 sandisk stick in and it recognized it just fine so looks like I'll grab one of those mini 128's and try that. I'll keep you guys posted.

Did you format the card before using it?
