The Consumer Reports Web site is filled with information about portable GPS units.
The Web site states that the "latest units are packing more navigation and entertainment features."
The good thing about the GPS devices is that you can carry them around with you, using them for finding your way on walks and bicycle rides.
Some companies that make the units are: Delphi, Garmin, Harman Kardon,
Jensen, Lowrance, Magellan, and Panasonic.
Consumer Reports buying advice, informative and thorough, details what you should look for in portable navigation devices.
Look for good navigation features over those of entertainment. Most important are things like the device saying street names and having it give you detour options for traffic jams.
A part of the buying guide on the Consumer Reports site includes a video that describes what GPS is and how you use it.
Isn't a wonderful feeling to know that when you have a device you'll be rerouted when you're lost.
You should be able to get a dependable system for under $300 according to the video.
Happy GPS shopping!
