2019 Equinox sd card error
I have a 2019 Equnox with navigation. I am getting a message that reads "SD CARD ERROR --LAUNCH NAV ON RADIO FOR DETAILS" when I go to the radio, the radio says "Once installed this NAV card can only be used for navigation in this vehicle:. I hit "CONFIRM" and it goes to my navigation map, but everytime I restart my car these messages come up all over again. As I said, my car has navigation and I have never had an issue prior to this. Two things have happened prior to this problem. The system did an automatic update and after that I cancelled my $35 a month ON STAR account since my car was purchased with navigation. My 2013 had navigation also and I did not need ON STAR for navigation. I'm not sure why I am getting this message. There is nothing in the manual or on line that I can find. Does anyone else have this or know what I can do to resolve it? Thank you.
