Navigation / カーナビ買いました

Last week I bought a portable navigation device (Garmin nüvi250) for my car because I had bonus this month and I did “holiday shopping” like an American. Although many cars in Japan have in-dash HDD car navigation systems costing over 300,000JPY with a receiver for Vehicle Information and Communication System (VICS), they were too expensive for me to afford. Nüvi250 has only a GPS receiver and power cables to be connected to a cigar socket or PC’s USB port, so it’s very cost-effective, costing only 38,500JPY! (about one tenth of the prices of traditional HDD car navi) More than that, it is not only sold within Japan but used worldwide, because Garmin is an American company. Nüvi250 is widely distributed in UK, European countries and the USA (in the USA, nüvi200 is sold instead of 250).

This device is simple and does not provide traffic information to avoid jamming routes, but GPS reception accuracy is very good. It displays an accurate position of where you are driving, keeps track of your driving routes, and calculates routes to destination very fast. Road maps are very simple, and easy to see while driving. It is very useful for 38,500JPY navigation device, as long as you use it just as a navigator.

As it is removable from your car, you can carry it with you anywhere, on the street or on the train, and you can install it to a rental car in a district far from your home town or even in a foreign country, just by plugging the power cable to its cigar socket. When you leave your car, you can put it off the car and in your pocket. There are no risks to be stolen.

Navigation is navigation. No functions more than navigation are necessary. PNDs are the most reasonable navigation system of today and more and more devices will be released in a few years, because you have only to pay the reasonable prices for necessary and sufficient capabilities.


今月のボーナスで、先週カーナビを買いました。といっても日本のクルマに多い30万円もする据え付け式のVICS付HDDナビなどとても買えないので、今はやりのポータブルナビ(PND)というやつです。米国のGarminという会社のnüvi250で、GPSレシーバーの付いた本体をシガーソケットに挿して使うタイプで、お値段はなんと38,500円!(普通のHDDナビの十分の一です)米国のメーカーなので、日本だけでなく、欧米など世界中で使われています(米国はnüvi200という名前です)。

シンプルなので、交通情報や渋滞情報を出してくれたりはしませんが、ナビとして使う限りでは、38,500円のものとしてはこれで十分です。GPSの捕捉精度も良く、位置を正確にとらえてくれますし、ルート計算もメチャ速! 地図もシンプルで見やすくなっています。
取り外し可能なので、道を歩いていても、電車の中でも、どこへでも持ち運べます。遠くの場所や海外でも、レンタカーに乗るとき、シガーソケットに差し込むだけで使えます。車から離れるときは取り外してポケットに入れることができるので、盗難の危険もありません。

ナビはナビ。ナビゲーション以上の機能は必要ありません。PNDは今日最も合理的なカーナビゲーションシステムだと思います。必要十分な機能に適正な値段を払えばいいわけで、今後数年でますます増えていくことでしょう。
