Nav section in top right quadrant, says insert sd. Every morning have a notification that says sd issue, install a valid sd. Had a a15 no name card from Amazon .. got an actual a7 Ford card off eBay, waiting for it to come Monday to see if it works. Car still getting between 19.9 and 22 avg mpg... 19.9 when I remote start a lot. 22 when I drive more. We've had a bunch of snow here in western NY past 2 weeks and it's enjoyable to drive when you click off the traction nanny!
