The current model I have includes a navigation disc that is supposed to solve the issue, but it doesn’t do anything when inserted. I’ve looked everywhere for an SD card, but I don’t believe the 2010 grand touring has one.
I’ve read online of people using the original navigation disc and it works for them. These are the only two I have. Wondering if there’s another disc I could attempt? Or if anyone knows of an SD location on this make? Any suggestions help. Planning on just replacing to whole display system if nothing else works.
