A car GPS navigator is undoubtedly a handy thing to help you navigate in unfamiliar terrain. As a result, the time for finding the right route and the right objects in a foreign city or area is significantly reduced. Even if you know a lot about such devices from the stories of friends, when choosing a device, you should be well versed in their main parameters and functions.
Instructions
Step 1
Choose a display size that suits you. They come in from 2, 7 to 7 inches with a resolution from 320x240 to 800x480 pixels. The larger the screen size and its resolution, the more visible the picture will be, and the more convenient it will be to use the navigator. Please note - the display must be equipped with an anti-reflective coating so that it can be used in bright sunlight. The presence of a touch function is at your discretion. Some people like it, others prefer buttons.
Step 2
Estimate the amount of memory, as well as the availability of maps of the regions you need. Inquire about the ability to download new maps. The maps loaded into them must be routable for the auto-routing feature to work properly. The optimal memory size of the purchased device should be at least 1 GB. Find out if there is a slot for additional memory cards.
Step 3
Find out how to mount the navigator in the car. The location of the device should be clearly visible to the driver, as well as ensure clear reception of the signal from the satellite. If the car has an opaque roof without a sunroof, and the windshield is athermal, a device with an external antenna is required. Try the convenience of using the buttons, pay attention to the presence of a cable for connecting to the cigarette lighter in the kit.
Step 4
Understand the automatic routing function. This is available in all modern models of navigators. In the best models, she can lay many route options: the shortest, optimal, comfortable, fast and others. At the same time, find out if the navigator can avoid traffic jams. Information about traffic jams is obtained on the Internet, but some models do not go out on their own, so they need to connect via a mobile phone or GPRS receiver.
Step 5
Check out additional features. One of the most useful is the ability to use the device as a hands-free kit for hands-free cell phone calls. Also, voice prompts of the system about important events on the way - about the approaching turn, about leaving the route, and others will be useful. There are also entertainment options - built-in mp3 players, video players, translators.
