There’s no need to worry about getting lost with Google Maps. After tapping the maps icon, Google will find your location. Ask it to direct you to the address you want and Google will give you a choice of routes. Tap the one you want and you're good to go.
Google Maps also lists points of interest ranging from cafes to petrol stations and you can simply ask it for directions. At any time you can stop a route by hitting the X at the bottom of the screen.
