Navigation Device
First Claim
1. A navigation system comprising a navigation device for receiving navigation data from a portable computing device, the navigation device comprising:
- a display;
at least one sensor configured to determine a reference direction, the reference direction being a direction relative to the display;
wireless communication means for wirelessly receiving data relating to a desired bearing from a portable computing device; and
a processing unit connected to the display, the at least one sensor and the wireless communication means, the processing unit being configured to;
receive a desired bearing from the wireless communication means;
receive the reference direction from the at least one sensor;
determine a desired direction based upon the reference direction and desired bearing; and
operate the display to display an indicium for indicating the desired direction relative to the display.

Abstract
The present invention is directed towards a navigation device (12) for receiving navigation data from a portable computing device (11). The navigation device (12) comprises a display (21) and at least one sensor (22, 23, 24) configured to determine a reference direction, the reference direction being a direction relative to the display (21). The navigation device (12) further comprises wireless communication means (25) for wirelessly receiving data relating to a desired bearing from a portable computing device (11) and a processing unit connected to the display (21), the at least one sensor (22, 23, 24) and the wireless communication means (25). The processing unit is configured to receive a desired bearing from the wireless communication means (25); receive the reference direction from the at least one sensor (22, 23, 24); determine a desired direction based upon the reference direction and desired bearing; and operate the display (21) to display an indicium for indicating the desired direction relative to the display (21). The navigation device (12) is particularly suitable for mounting on bicycles.
