What makes a good GPS? This question will come out when you are going to buy a GPS device. How do you
know the quality and the capability of various GPS systems in the market? Is it true that the cheaper one is
better? Do you need to check for more features?
Actually it is same important for choosing the GPS device as any other electronics device. You need to know
what you need, what you are looking for. Do you really need this when you are traveling? Or od you really need
to help you when you are in traffic jam?
Firstly the screen size is very important for GPS device. A larger screen will better for you, because it could
provide a larger map view so that you could know where you are and what’s coming up. But the size of screen
can not be too large, since you do not want to carry something like theatre around your dashboard. So the size
around 3.5 to 4.7 inches will be ok. In fact, most of the GPS device have touch screen. For this function you need
to check out the quality and sensitivity of the screen.
There is another thing you need to pay attention to. That’s the battery life. A sufficient battery life could last
relatively long journeys. Most of the GPS systems come with a car charger. Usually the battery could last 4 to 7
hours.
Actually, there is another device, which has GPS system, as well as dvd player, blue tooth, and ipod ready. It’s
multifunctional. If you need some entertainment system, you could take a look at this.
