Instructions

Step 1

Consider an internal device if you are buying a new car. Dealerships may offer good incentives for GPS systems. If you want something you can use in your current vehicle or in multiple cars, companies such as Tom Tom, Acer, Co Pilot, Pioneer and On Star offer portable systems with many options.
Step 2

Choose features. The basic system has a simple screen display that pinpoints your location and your destination. Advanced systems present a more descriptive street display and a sound function that guides you while you drive. Some systems include speed camera and radar monitoring.
Step 3

Research online before buying. Explore Web sites for various brands. Discover what models cost and what features they include. Then compare the data to see who is offering the best deals.
Step 4

Go to your local electronics store. Ask to test the product at the store before you purchase it.

Tips & Warnings

Check for monthly fees. Some GPS systems have monthly fees; others do not.
Use the cost of the GPS system as a tax deduction if you are using it for business purposes.
