Five Things to Consider Before Buying a GPS System 6



Since I'm plugging it into my car anyway, does battery life really matter?

Yes. While it may seem to be a moot point since a portable GPS plugs right into your car's 12-volt power plug, you'll still want to consider battery life in your GPS purchase. Why? Well, first off, those power chords that go from a GPS device to the adapter are not only mighty ugly and tangly -- thus cluttering up your otherwise sexy dashboard -- but they're also downright dangerous when they inevitably get caught up in your gear shift.

Also, if you plan to do any walking, you'll want a device with power that'll last long enough to be truly "on-the-go." GPS services on cell phones take up a lot of juice, too, so if you plan on using your mobile to make phone calls on the next long drive, you can save power by turning off other wireless apps like Wi-Fi and Bluetooth.
