Speed Limit readouts conflict

[PA Bob]

My 2021 MME is getting more & more glitchy. One befuddling thing is that the speed limit warning on the monitor screen often conflicts with the screen on the dash. You’d think the data come from the same input so it’s be impossible to get different readouts.
I planned on keeping this car many years, but the software is getting obsolete.

If you use GoogleMaps with Android Auto, that displays on the center screen while the dash is from Ford Nav.

I thought the speed limit displayed on the dash is what the car sees and uses the database to fill in when camera doesn’t see one.

Sure. Database / Ford Nav, i.e from Ford. Versus the center screen if you are using GoogleMaps with Android Auto is from there. Hence why they don't match, often. We did a 5,400 mile drive and they were more often in discrepancy then matching.

This seems to be getting worse. Using CarPlay with a destination set on Wednesday, the speed limits were rarely in agreement.
