Abstract

When an area corresponding to area information is determined to use a default font, an ECU displays characters by using the default font stored in a ROM. When an area corresponding to area information is determined to not use a default font, the ECU reads out an exclusive font corresponding to the area to store it in a RAM, and displays characters by using the exclusive font stored in the RAM.

Description

field of invention

[0001] The present invention relates to a map display device for displaying characters by selecting fonts used in an area, and to a navigation system using the map display device. Background of the invention

[0002] A conventional navigation system displays characters by using a font selected by a user. The navigation system described in Patent Document 1 has three display modes (Kanji mode, Romaji mode, and Katakana mode); characters are displayed based on the mode selected by the user.

[0003] Conventional navigation systems are assumed to be used only in one country (eg, Japan) and not in other countries (eg, China, etc.); such systems cannot display characters used in other countries. Thus, a navigation system for a particular language region is manufactured to contain specific characters for that particular language region. This can cause design or cost issues.
