I have a 2021 RS7 on order and cannot find any reference to SD card (& slot). My problem is then, how do I import music into media if I cannot use a SD card? My 2015 S7 and 2018 SQ5 both have SD card slots and I imported from the card. Also, my computer (where music resides) only has USB-C ports so I cannot plug 'old' USB-A sticks into the computer (yes USB-C to USB-A dongles exist). Can anyone tell how to load my music into 2021 RS7 media?
