Good day, first time posting, new owner of a 2019 GT CX5, trying to do the update and I*m not having any luck with my car reading the usb drive, tried two different ones. Any ideas?
Did you disconnect all paired devices?
Just a guess.
If your car is still within 3yr/36k warranty, and your dealer refused to update your firmware, just tell them you ran into all sort of glitches with it. They will do it. They can charge Mazda for the labor. Why not?
Dealers are not authorized to update firmware w/o customers explicitly complaining about it. So, do complain....
