Yes Mapquest is tough with FREE turn by turn, but The App Route 66 collaborated with TomTom to produce a new Android app, appropriately titled Route 66 Maps + Navigation…See Details.
@TatWza

The App brings augmented reality to GPS navigation, especially a feature called Follow Me that allows real drivers to follow virtual cars turn for turn. Follow Me uses your smartphone or tablet’s camera to display real-time video of the road ahead, and places a virtual 3D car directly in front of you on your route, the car’s rear lights indicate when to turn right or left. Maps + Navigation also includes simultaneous voice directions in 57 languages, up-to-date TomTom maps of 100 countries with 3D graphics, and multitouch gesture control. You can get your hands on the app via Android Market soon
