本发明提供一种导航设备(200)，其包含：一路径计算模块(298)，其可操作以计算一自一出发位置至一目的地位置之路径(288)；一再现模块(302)，其经组态以使用数码地图数据来产生该路径(288)之影像以供向一用户显示；及一路径预览模块(304)，其可操作以向该用户提供该计算出之路径(288)之一预览；其特征在于：该路径预览模块(304)可操作以将该计算出之路径分割成会合段及道路段，且经组态以控制该再现模块(302)以一比表示该等会合段(312)内之位置之影像为高的显示速度来显示表示该等道路段(314)内之位置之影像。

A navigation device (200) comprising: a route calculation module (298) operable to calculate a route (288) from a start location to a destination location; a rendering module (302) configured to use digital map data to generate images of said route (288) for display to a user; and a route preview module (304) operable to provide the user with a preview of the calculated route (288), characterised in that: the route preview module (304) is operable to divide said calculated route into junction segments and road segments, and is configured to control said rendering module (302) to display images representative of locations within said road segments (314) at a higher display speed than images representative of locations within said junction segments (312).
