Most models of car GPS-navigators can not only determine their (i.e. car) location and inform the driver about it by displaying the coordinates of latitude and longitude, but also many other things, such as

• Paving the best route to your destination and quickly change it if during the movement you (intentionally or unintentionally) have deviated from it;
• Remember the route you were driving and if necessary, recall it from the memory and display it on the screen;
• show on the display the current direction of travel;
• calculate and display a number of navigation parameters (current speed, average travel speed, time you are en route, time left to reach the destination at the current speed, etc.)
• to give voice prompts during the motion;
• to give a warning signal in case of deviation from the planned route, and also to inform the user about the fact of passing the intermediate control point and arrival at the finish point;
• inform about fulfillment of traffic rules, time of sunrise and sunset, etc.

Many modern GPS navigators have already moved beyond the scope of highly specialized devices, and they can rather be called a special kind of mini-computers, which additionally have a GPS chip and navigation software, so, in addition to the above-mentioned direct navigation functions, they are able to perform a number of other functions. For example, to play files of different formats, including multimedia, receive TV signals and much more. But let’s not get ahead of ourselves now, because we will talk about all of this in more detail below.
