Today’s car navigation systems are increasingly becoming more sophisticated and offering a wider range of features. And to the delight of users’ prices continue to come down offering expanded capabilities for the budget conscious.

A good way to determine what type of GPS unit is best suited for you is to consider the type of driving you do. Do you need GPS for casually navigating from point to point such as a day trip to Boston? Do you follow a predetermined route on a regular basis such as a delivery vehicle that stops at the same locations? Are you traveling to multiple locations and need to determine the quickest, most efficient, way to get to each of your stops? Do you need portability, the ability to take the unit out of the car and carry it with you so you can access the points of interest database?

Each of these different requirements can have an impact on the size, memory, and maps included in the unit that’s right for you.

The primary difference between many models is the amount of memory included. The amount of memory determines the number and size of maps, and the number of separate routes that can be programmed. Users that wish to use the MP3 player will want additional memory for song storage in addition to mapping storage

Another differentiating feature is screen size. Larger screens can support higher resolution and more colors and, depending on in car placement, easier viewing and usability. Users that have digital cameras and want to view their pictures on the GPS screen as they travel may want a larger screen but will almost certainly want higher resolution and better color support.

Less expensive models provide excellent car navigation for the casual traveler but more frequent travelers may need to store multiple routes, and will need more memory. Determine where in your vehicle the unit will mount, screen size and the ability to clearly see and reach the buttons is important. Larger screens are easily readable but not very portable. If you are a casual traveler and want to use your GPS to visit a destination and once there remove the unit from the car and carry it with you to locate historic sites, restaurants, or hotels you may be willing to use a smaller screen in favor of the units light weight and portability.

Additional features can help you determine the unit that’s best suited for all your traveling needs. More memory and smart card ports allow the user to add additional maps. Software choices include comprehensive travel guides with hotels, restaurants, landmarks, and thousands of other points of interest including the ability to add your own. Additional capabilities include audio book and MP3 players that will connect to the cars sound system. Higher end models also have Bluetooth compatibility for hands free phone use. Optional services also include features such as language translation or live traffic alerts.
Thinking carefully about your traveling needs is important to determining the right GPS unit for you. Your car navigation system is fast becoming a comprehensive multi-media entertainment center and guide to traveling.
