Abstract
A navigational device comprising navigational electronics and an improved menu-driven user interface. The navigational electronics are operable for receiving navigation signals from a source, for calculating a position of the device as a function of the signals, and for providing directions to a desired location. The user interface is operable for controlling certain functions of the device and includes a rotary wheel that may be moved in two directions with no mechanical limits for selecting at least one of the functions. In preferred forms, the rotary wheel is rotated up or down to highlight functions and then pushed in to selected a highlighted function.
