Determining the coordinates of your car, laying the shortest route to bypass traffic jams and finding the desired address is impossible without a GPS navigator. It should be selected according to the required display size, firmware, and several other parameters.
Software
The "heart" of any navigation device is its program. It is it that serves as a link with the satellites, determines its coordinates thanks to them, and also draws a line from point A to point B - the beginning and end of the path. Most navigators are equipped with a voice warning of upcoming turns, other route changes, as well as a warning against traffic jams. Depending on where you plan to travel: around the city and Russia, on tourist trips around the continent - it is recommended to buy devices from a Russian or foreign manufacturer that installs the appropriate maps and regularly releases free updates.
Detailing is also an important parameter - the ability to maximize the map up to the drawing of small streets and houses. Moscow and St. Petersburg are visible with the smallest details in absolutely all navigators, but the detailing of other cities is not available to everyone.
The software of some devices allows you to remember frequently made routes, as well as to keep in memory snack bars, gas stations, traffic police posts and some other key points for the motorist. Some of them are capable of detecting speed detection radars located further along the road ahead of time.
additional characteristics
The next parameter is performance, which includes the stability of the communication signal with satellites, processor power and the amount of stored information. To ensure that the signal is not interrupted due to athermal glasses, the navigation device must be connected to an antenna brought out to the outside. The speed of processing the response from the satellite, scrolling and zooming the loaded maps, as well as the built-in entertainment functions: photo, video and other multimedia applications depends on this, as well as on the power of the processor.
A detailed map can take up to 1 GB of memory, so its size in the navigator should be as large as possible.
The navigation device can have a display of 5 inches - this is enough to display your location, or more than 7 inches - then the smallest details will be clearly visible, and the screen itself will contain as much information as possible. A high resolution will provide a clear picture: the larger the screen, the higher the resolution should be. The anti-glare coating will save the driver from the need to look closely at the display and will be a plus on a sunny day.
