Two days after purchasing a new 2020 gmc acadia i get an error on the display "sd card removed" along with various other error messages. dealer talks to gmc tech line and they advise to replace radio. radio was replaced and errors began same day i picked it up. dealer is replacing radio again, but unsure if this will fix the issue. the vehicle does not work as intended as when you press the nav button various error messages pop up and navigation does not work.
