Weigh GPS Pricing

• You can purchase a used portable navigation for under $100 for your car. If you are buying a brand-new car and want a navigation system, you usually have to go with a top-of-the-line model and packages that you may not need. This can cost you thousands of dollars. In addition, updating your navigation for a built-in system often requires the purchase of an updated CD.
  
  

Factor in Mobility and Convenience

• A portable GPS can be moved from car to car or taken with you while hiking. Although a built-in GPS cannot be moved, it is conveniently located in your car. The built-in option also offers a larger viewing screen, helping you to find your way without distraction. Many built-in GPS systems also serve as a DVD readable drive (you can watch movies if the vehicle is parked).
  
  

Bottom Line

• Decide whether you should get a portable GPS or one that is already built in by determining your costs and convenience. If you have only one car and can afford the option of a built-in model, the purchase would be beneficial. If you want to save money and would enjoy the versatility of the the mobile GPS, purchase one that serves all your needs.
