Navigation for Car (Fremont)

Looking for an old school type of navigation/ GPS system that can connect to a car through a car lighter. I need one for my father-in-law he doesn't want to change from his flip phone he's old school and electronics are too much for him to handle and he refuses to upgrade.continues with his flip phone so I was looking to hopefully get him connected with at least a navigation for his car so he doesn't keep getting lost
