A navigation app displayed on a car’s screen doesn’t necessarily store its information in the vehicle.
In that arrangement, navigation history and saved destinations may remain associated with the phone or the navigation account rather than the vehicle’s built-in system.
The Federal Trade Commission has warned consumers that vehicle electronics can retain personal information, including navigation destinations, phone contacts, app login information, and garage door codes.
Look for settings labeled Navigation, Destinations, Favorites, Personal Information, Privacy, or Recent Searches.
Consumer Reports recommends checking individual system menus and manufacturer accounts when clearing a vehicle’s personal information.
