As far as we know, there are many car gps navigations units, and they are complex, so it's impossible for a unprofessional person to choose the right one for her/his car. Then I'm pleasure to share the experience on how to choose the best CAR GPS navigation for the auto in this chapter.
Generally speaking, if you consider the price, portable GPS navigation systems will be the best option, they are cheaper than build-in GPS. What's more, it's easy to install, carry and transfer it to another auto. They are simply mounted on the dashboard and powered via the cigarette lighter in the car.
So I will show the way to configure the portable GPS navigation for your car in the first part, please refer to the informations below.
Firstly, Determine how much you want to spend on portable GPS system for your auto, based on your personal financial situation. This will help you narrow down your choices in GPS systems, and setting a spending limit. It will help consumers avoid over-spending when buying a GPS navigation system.
Secondly, List portable GPS navigation system features that you're seeking, like the United States map in details, voice guidance, a small color screen, touch screen, mounting suction cup, Bluetooth capabilities for use as a hands-free cell phone accessory and power adapter. This kind of portable GPS navigation system is suitable for occasional use. They are very basic and will be able to assist you during driving.
Thirdly, Visit as many online retailers or visit a few nearby stores as you want to look at the available GPS navigation systems. When shopping for GPS navigation units, look for units that fit your established criteria. Write down price, features, GPS brand and GPS model name/number of each navigation unit that fits the criteria that you established for purchasing your new GPS navigation system.
Forthly, A major drawback of the portable GPS navigation system is the lack of an internal compass, accelerometer or a device used to measure the car's speed. Without this feature, it does not navigate as accurately as a build-in GPS system when there is no GPS signal. If you live in an area where there are a lot of tunnels, high rises, or uses the GPS very frequently, it is important to buy a more sophisticated portable GPS system that has a build-in accelerometer.
Lastly, Decide which GPS system you will purchase based on the price, features and your hobby. Then purchase the GPS navigation system unit at the store or online retailer.
