PORTABLE TERMINAL, NAVIGATION SYSTEM, AND STORAGE MEDIUM STORING PROGRAM
First Claim
1. A portable terminal comprising:
- a wireless communication unit which performs transmission and reception of data with a portable external instrument by wireless communication;
a control unit which requests navigation data from the portable external instrument at a previously set request timing, and obtains the navigation data from the portable external instrument by using the wireless communication unit;
a display unit which performs a display based on a control signal from the control unit; and
a detection unit which detects an orientation,wherein the control unit (i) allows the display unit to display orientation information included in the navigation data obtained from the wireless communication unit, in accordance with orientation data obtained based on a signal from the detection unit, and (ii) allows the display unit to display navigation data that is simple in comparison with the navigation data displayed by the portable external instrument, the simple navigation data including at least a display in a travelling direction, based on the navigation data obtained from the portable external instrument by the wireless communication unit.
