As far as I know, they don't come with navigation so you'll need to connect to a device and use either apple Maps or Google Maps. Plugshare is an app on the phone too and not an integrated system in the Bolt.
There definitely doesn't seem to be a navigation button in the menu screen in the videos that I've seen. PlugShare is definitely an app you have to utilize through your phone however. Or you can go online and view the map as well on your desktop/laptop.
