NTFS formatted USB sticks work!
I have not seen this reported before, so if this is common knowledge, then I apologize in advance.
I don't know if the change was recent or not as I never tried it before, but my car does read NTFS formatted USB sticks!
I recently got a 64GB USB stick formatted as exFAT32 and the car completely refuses to recognize it.
Windows would not format the 64GB stick as FAT32 (it complains it's too big), so just for giggles, I formatted it as NTFS and tried it and it worked!
I'm able to play music from this USB stick in the arm rest port and also import music from it in the glove box port!
So now I have 64GB of music accessible to me while I drive; That's enough for a LOT of driving!
