Another feature of this extension is Get Directions.
Switch to this section by selecting the second tab in the side drawer window. QB Maps allows users to select a source and a destination by either selecting a pin/marker and choosing the radio button on the info-window, or by typing in the address (with autocomplete enabled).
Note
If you're using your current location, a red pin appears, and selecting it offers the same origin and destination choices.

After selecting a valid source and destination, you can get directions both on the map and in text format. By selecting the Open Google maps button, you can open the route in the native Google Maps app on a mobile device or the Google Maps web app on a desktop browser.

If you still want the pins from the other locations to show, you can include the &ddShowAll=True parameter in the URL to continue displaying those pins while the directions are shown.
To get directions between multiple locations, learn more about the MultiSelect feature of QB Maps.
