Choosing A Car Global Positioning System?

Answer 1

These days, global positioning systems can be found in just about every car and phone in the country. They're extremely popular because they provide expert, step by step navigation. Standalone GPS units can cost $300, or more, however, and they vary greatly in quality.

Finding a good global positioning system requires research. One of the most important things to look at is whether the phone offers a good selection of points of interest, often abbreviated in product descriptions as POI. Most global positioning systems have a built in database of points of interest, so it's very important to choose one with an extensive and up to date list. Points of interest are often arranged by category, for instance food, gas, and hotels. They can be updated regularly in some instances by hooking a GPS unit up to a computer via a USB cable.

In addition to a full point of interest system, a good global positioning system should be able to regularly update itself for traffic information. If a certain area has high congestion rates, the global positioning system should be able to reroute around the traffic. This is a relatively new feature and utilizes a radio receiver built into the GPS system or live information from the same satellite that regularly updates the position of the device itself. Traffic rerouting can be extremely useful and can save a tremendous amount of time under the right circumstances.

Screen size is another important factor when choosing a GPS system. Screens vary in size because some drivers prefer a full view for easier navigation while other drivers prefer a smaller screen to avoid obscuring the view of the road. Although screen size varies, almost every GPS on the market uses a touchscreen although there are a few models available that use keyboards instead.

A global positioning system may have a number of extra features, including a built in media player or voice guidance. Voice guidance is particularly important as it allows drivers to keep their eyes on the road while using a global positioning system. Some voice guidance systems give turn by turn directions and use special technology to read street names, while others provide a simple left or right command for the driver to follow.

Finding the right GPS will take research and some careful reading. Drivers who take the time to do this will find a high quality, useful device.
