Before buying a portable navigator, you need to figure out how and for what you will use it. Usually navigators are used to plot the desired route and find out the current location of the object.
Instructions
Step 1
Find out the type of GPS receiver installed in your navigator. Currently, 12-channel receivers are relevant. They allow you to quickly and accurately determine the coordinates, even in cases where the signal is distorted by various obstacles, such as walls or trees.
Step 2
Check out the display quality. First, pay attention to its size. You should not buy a navigator with a display less than 7 inches. Naturally, in this case we are talking about a portable car navigator. The display must have an anti-reflective coating. This will allow you to work with the device even in bright sunlight.
Step 3
Check the performance of the touchpad. In this case, you need to pay attention to the following parameters: ease of entering information (stylus); responsiveness of the device; the speed of changing the picture and loading a new map.
Step 4
Check if there is a slot for installing a memory card. If your navigator supports a map with more memory, you can load more information into it. This usually allows you to download topographic and road maps, on which the necessary objects will be marked.
Step 5
Consider the need for audible alarms in your portable navigator. If this feature is important to you, then purchase the appropriate device. Some car navigators are equipped with a BlueTooth module. It is required to establish communication between the device and the mobile phone. This will allow you to make phone calls without any problems using the hands-free mode.
Step 6
Multimedia players and other programs are built into modern navigators. Find out the need for these functions and purchase the right GPS navigator.
