Did I already mention about these cool car navigation systems inside typical Japanese-owned cars. Car navigation systems are called "kaanabi" (Car Navi) in Japanese and are usually bought and installed separately. Car navis provide you with a GPS map and lets you find your current location, as well as your desired destination, and give you the right directions on how to get there. It also talks by itself by the way. "Turn right!" "Turn left!". It also has tons of other features that are convenient for road travellers.
