Typically the infotainment (in the olden days referred to as a radio) can handle the size of a thumb drive that was prevalent when it was designed. I have a manual tuner radio in my TR7 with SSD and USB slots, looks like a period piece (1980) except for the slots and it only handles up to 4 Mb. Fortunately there is no problem getting a less than (even 512 Mb. USB) for a few bucks from Hong Kong etc. often with free shipping.
