We used Street Atlas thru ver 10; that one was a bummer but we always feed the Garmin GPSr into Street Atlas. Switched over to Garmin mapsource for routing now and then load into the GPSr which has a much smaller footprint then a lap top for use in a pick up. Down side is mapsource doesn't take real time input. Also the newer Garmin GPSrs won't load correctly from mapsource so you have to transfer the route to Garmins Base camp to load the GPS. Both mapsource and base camp are free from Garmin. Haven't tried them with windows 10.
