Recently I have updated my mobile version to iOS 18, since the day maps are not working in Apple Car Play since the update. The car display shows the message directions are not available in your location. Before the update it was working perfectly fine.

I am using iPhone 13 and recently I have updated the OS to iOS 18.0. Since that day, maps are showing blank on the car when I connect through the Apple CarPlay, and a message is displayed after a few minutes on the car screen stating the location information is not available. When I start the car immediately maps are turning to blank on the car display.
