Abstract

A single-handed operating navigation apparatus allows aims to provide rapid scanning and confirmation of selection items single-handed. It mainly includes a base, a screen, a rotary disk and at least one pushbutton. The base contains a navigation host and a GPS satellite receiver. The screen aims to display navigation information. The rotary disk can rotate continuously clockwise or counterclockwise to provide fast scanning and operation of the selection items. The pushbutton includes at least one selection item confirmation button and one selection item activation button. The navigation apparatus thus formed enables users to rapidly do navigation setting single-handed.
