Navigation systems are currently quite popular. When choosing a navigator - your future assistant on the road - you need to pay special attention to its main parameters and functions.
Instructions
Step 1
First, take a look at the display of your navigation device. It is he who will give you all the information you need on the way. It should be reasonably large. The display resolution must be high. Optionally, you can choose a diagonal. It varies from 2, 7 to 7 cm. Ask if the screen has an anti-reflective coating - it allows the driver to see the image well even in bright sunny weather. At the moment, you can purchase a navigator that has a touch screen. This is very convenient, since the device is controlled directly through the device screen.
Step 2
Then you can proceed to the choice of the card. This parameter is considered the most important and difficult. Ultimately, the quality and efficiency of the navigator depends on it. Decide in advance which region of the map you will need. Also ask if they are preloaded into the device you like. Almost all navigators have a route planning function. This is why it is best to use routed cards. Otherwise, you will only see your destination on the navigator without plotting an optimal route.
Step 3
Purchase only those maps that have a high level of detail and contain a lot of information about objects. Their size can be about 1GB. The minimum size of a cartographic map is 64 MB. It is better to give preference to those navigation systems that have a slot for flash cards. Additional memory will be required to load media files into the navigator. You can also easily upload a 3D image for maps there.
Step 4
Of course, the appearance of the device is also important. Pay attention to the types of mounting the navigator in the car. The receiver must be located so that the driver can see all the information without any problems. There must also be a clear reception of the navigation signal. It is best to purchase a navigator that has the ability to connect to an external car antenna
