Many navigational GPS systems are very robust in their features. They give drivers directions, provide directories to places such as hospitals and restaurants. They also provide street and highway maps. Voice directions will lead individuals directly to their destination. With so many advantages, it seems impossible to imagine that we have ever gotten along without them. The top-of-the-line GPS systems and the most expensive ones have extra special features, such as street maps that are in full color and 3-D, traffic alerts, that will let you know if there's an accident or if traffic is backed up. They also will help re-route you to help you get to your destination. Some of them also come with the ability to use the cell phone without using one's hands. They also have touch screens, FM transmitters and even widescreens.

The GPS system that you purchase will be determined based on your budget and on your personal needs. There are a few ways to get a navigational system in your car. The first option and probably the most simple, is to purchase a vehicle that already has a GPS system installed. For those who perhaps have an older car or just did not purchase a car with a navigational system when they were in the market for a vehicle, may want to go with purchasing and having installed an aftermarket system. This will be installed and your standard radio system will be taken out. A third option is to simply purchase a GPS system that is portable and that can be placed in your car. You can take it with you or simply mount it on your dashboard.

The most expensive option is probably to purchase a vehicle that already has a GPS system. However, you are likely to get a very good model. Often times these come with the LCD screens that are big, this helps a great deal when you*re looking at maps. These types of systems are also integrated with other things in the car such as the radio, the built-in cell phone, and climate control. One disadvantage of purchasing a car with a GPS navigational system already installed is that when new ones come out, it is not as simple to upgrade it.

Purchasing an aftermarket GPS system and then having it installed is a second option. These are of very high quality as well and usually come with a navigation system, a stereo and a CD or even a DVD player. These are great to use in recreational of videos as well as cars, SUVs and minivans. They can be kind of expensive and you will need to have someone install them professionally.

The last option and probably the least expensive is the portable GPS system. It gives you a lot of flexibility. You can choose a more expensive option because you will not have to pay for installation and you also can take them anywhere, which makes it great, especially for individuals who travel a lot or use rental cars.
