If you often travel to new places, have trouble reading maps, or simply hate to ask for directions, you might want to consider a portable GPS navigation system. Once you give it a destination, the system can plot out a route, deliver spoken directions, and display each turn as you drive, or in some cases, walk. Most units let you choose guidance options that include plotting the shortest, fastest, and even a toll-free route. An internal database also includes common points of interest such as gas stations and ATMs, and the nav system can route you to the nearest one. You can even choose a nearby restaurant by the type of food.
Although not always as easy to use as the in-dash systems available on many new vehicles, portable systems are catching up. Features like internal, rechargeable batteries and pre-loaded North America map databases are now commonly included on budget systems. More premium features such as real-time traffic reporting are becoming available on more affordable units, although those often require additional hardware.
Portables have the distinct advantage of being easy to move from car to car, enabling a family to share a unit or lend it to others. Their low weight and small size are well suited to long-distance business travel and vacations by plane (for use in a rental car when you arrive), or for walking and biking tours (for use as a handheld device).
And with prices from about $200 to $650, portable units are much less expensive than the typical price tag of up to $2,000 for an integrated, in-dash factory system.
