This invention relates to a display method and apparatus in a navigation system. More specifically, this invention relates to a navigation-based method and apparatus to provide guidance information to a driver without repeatedly performing route recalculation when the driver makes slight deviation from the road he or she is travelling on. In one embodiment of the present invention, guidance information is displayed on a user interface without generating a route. For example, when a vehicle is travelling either on a freeway or a surface road, a distance indicator provides distance information to nearby freeway junctions or streets. In another embodiment, when the vehicle is deviated from a calculated route, a route deviation detecting unit may detect whether the vehicle is deviating from the calculated route to a predetermined extent. If not, the original calculated route will not be recalculated.
