The points of interests on a GPS device are also related to the GPS checkpoint function. The GPS checkpoint function refers to the points of reference, or way points, that help people trace their way back from a starting point.
All of the competing GPS brands like Garmin use a POI feature as one of their marketing advantages. The more GPS POIs their item has, the better and more useful the device is to the consumer. Garmin, for example, in their Nuvi series, offers six million points of interest in each of its models. GPS Magellan brand GPS devices are also loaded with millions and millions of points of interest that are quite a useful GPS navigation feature.
Now, if you are worried about how much GPS POI will cost you, you shouldn't because the GPS points of interest feature is free and, as mentioned earlier, is part of the features of the GPS device. In fact, you can even update your POI database for free. Some GPS software also includes updates for your GPS POIs. And, just in case that you are faced with a situation in which you have to pay for the update, you can still smile because it doesn't really cost much. And, if you think about the benefits you can get in return, then updating your POIs is simply priceless!
