You may need to increase the zoom factor if you are far away from a road. Try zooming different distances and facing different directions when you zoom. It's a lot of fun to visit an area miles away! Table of zoom factors: 1) - 60 ft. 2) - 120 ft. 3) - 240 ft. 4) - 360 ft. 5) - 480 ft. 10) - 2880 ft. 12) - 1 mile 24) - 10 miles 31) - 100 miles 34) - 1000 miles The best setting for urban areas is generally zoom factor="2", though some high-density areas such as Manhattan or the East-end may benefit from zoom factor="1" or even zoom factor="0". (zoom factor="0" may exhibit strange behavior, kind of like taking a picture of the back of your head!) For suburban areas minimum zoom factor should roughly range from 3 - 6, depending upon the distance between roads. Rural areas will generally require higher zoom factors.
