Talking about GPS buying tips we should first of all pay attention to the memory. Pay big attention to this parameter, because the more memory there is in car navigator, the better. Now, not a secret that the more fine details on the map, the more it will consume memory, plus the same automatic routing on the map, too, contributes to memory consumption of navigator. Therefore, the size of the memory map must be not less than 64 MB.

Automatic Routing: this feature is actually common to all modern navigators. Using auto route you can easily get from point A to point B. We would like to note that the automatic routing works only on special maps, which contain more complete information on roundabouts and road signs. Availability of voice prompts is a very handy feature, which in time will inform you of an impending turn or on arrival to the destination. In modern receivers, sound signals are replaced by voice prompts telling you how many meters before turning or to the end point left.

GPS buying tips and Waypoints: there must be at least five hundred waypoints. Description of each point includes the name (it is recommended to introduce at least six characters) and an icon to be displayed on the map. Waypoint can be used as the final destination for route calculation. Points of Interest: Originally in memory there is thousands of POI, which include gas stations, traffic police posts, car repair shops, restaurants, hotels, entertainment centers, etc. Library of points can be supplemented with a CD.

GPS buying tips and tracks: This is the path traversed by the user, is always automatically recorded in the memory unit. Number of points which are stored in the track must be at least 2000. In the current model, this parameter is increased to 10 000. Some receivers allow you to customize the frequency of entry points, by selecting one of the parameters of the recording period: automatically, by time or distance between adjacent points. In many receivers there is implemented original function, allowing the user to repeat the distance traveled in both directions.

Availability of computer interface: Despite the self-contained of car GPS-devices, they must be connected to a personal computer; using this interface you can save points, tracks and routes on your computer. You can also download cards, points, routes, previously stored or received from other users of GPS-navigators. External power supply: Connection is usually done in the cigarette lighter socket.

Attention is drawn to the presence of the relevant cables included. Large screen: the driver must clearly and rapidly perceive the information from the GPS-receivers. Therefore, screen sizes and fonts are particularly important. External antenna: The antenna, mounted on the roof, provides better and more reliable reception, allowing you to determine the position, even in dense woods or near tall buildings. GPS buying tips and fixing: Pay particular attention to fastening the navigator, because it is important to remember that for safe driving and a comfortable navigation automobile navigator must be securely fixed in the car. Focusing on these criteria, you can make the right choice of the GPS.
