In this paper, the feasibility of an unmanned vehicle driving using a commercial navigator is evaluated. Using TBT data and GPS data the distance of a speed bump is estimated. The current commercial navigator starts to give TBT data in a specified region but no distance information. It is hard to apply TBT alone. Because of GPS error and the delay output for abrupt changes of the driving path. The integration of camera to overcome this drawback is under researching.
