You can set all sorts of preferences in the Beeline app. If you’d like to switch between 12 and 24 hour clock, between mph and km/h, and between enabling auto rerouting or not, just head to the ‘settings’ menu and set your preferences there. 

If you’re using Route Mode, you can also set preferences about which roads you would like to avoid, like motorways and toll roads. To set these preferences, open the route planning screen and tap the top right ‘...’ button.
