What to look for in a GPS?
When we talk about GPS, the most common use is the vehicle. Having a device capable of locating addresses and indicating how to reach them accurately attached to the windshield glass is like having a copilot always ready to help you get your way.
There are several types of vehicular GPS . First, look for the size you are comfortable with. The number of inches on the screen is usually not a problem, as the devices are able to narrate, in a voice, what you need to do. For people with vision problems, devices with larger screens can be more useful, especially when typing the destination address on the touchscreen.
But, the main point, is the coverage area . Any GPS must be prepared to cover the capital's cities, but if your plan is to travel inland and explore new cities, it is better to choose one with many municipalities and states registered. Another determining factor is the points of interest , turning the device into a powerful tourist guide when it comes to finding supermarkets, gas stations and other establishments.
Also pay attention to the type of map display. Some devices are able to show 3D map elements , helping to identify monuments and large buildings that can serve as a reference when finding your way. Finally, the speed camera alert on many models is an extra that avoids fines and reminds you that you must always respect the speed limit.
