1. A Personal Navigation Device (PND) comprising:
- a Global Positioning System (GPS) module, for generating a current location value;
a processing module, coupled to the GPS module, for comparing the current location value and a plurality of hint points; and
an user interface module, coupled to the processing module and providing a display device, wherein when a difference between the current location value and any hint point is less than a first threshold, the display device displays stored real image data corresponding to the hint point.

Abstract
A Personal Navigation Device (PND) includes: a Global Positioning System (GPS) module, a processing module, and a user interface module. The GPS module generates a current location value. The processing module, which is coupled to the GPS module, is utilized for comparing the current location value and a plurality of hint points. The user interface module, which is coupled to the processing module, provides a display device. When a difference between the current location value and any hint point is less than a first threshold, the display device displays stored real image data corresponding to the hint point.
