Yesterday I got a message on dash of my 2019 Premier, SD card removed. When I try to use my navigation the screen says down loading maps then goes to SD card removed. I checked an the card was still in the slot. I removed it to make sure the switch on the sad card was in the correct position. Checked the fuse associated with navigation and it was good. Still get a “SD card removed” at every start up. Also the USB ports above the wireless charger no longer operate. The 12v aux socket works. Anyone have any ideas as to what could cause this. Any suggestions appreciated.
