I had a galaxy note 9. Connected to my 2021 Honda CR-V no issues. I got a new phone 2 weeks ago, a galaxy s21 ultra. Android auto will not work. When I plug in cord to connect I get error message saying "not supported" and that is using cord phone came with. Also tried 2 other high data transfer rate cords. Have tried everything Google, Samsung, and Verizon have had me try no no avail. My phone is worthless without android auto.
