First tried a 512gb USB stick formatted with a 64gb partition - car wouldn't even see it.

Now I'm using a 64gb SD card via a SD card reader with USB C.

Car just says "no supported files" when I insert it, and "please connect the usb device containing the update software" when I press update via USB.

I freshly formatted the SD card to exFAT and let the Kia Navigation Updater software do it's thing too. I can see all the files (9ccNC_NAVI_MAP_EUR_18_47_48_420_942_0.enc, CCNC_SYSTEM_ALL_EUR_0000_00_001_002_251118_222153.enc etc.) on the root of the SD card when I plug into my PC.

The car is on, in parked mode. I've tried while AC charging and not AC charging (I think...I'm always plugged in at home :))

Any ideas reddit? Thanks.
