GPS Navigation Systems are a lot like DVRs (better known as
TiVo). People who don't own them fail to understand why they're
such a big deal, and those who have them can't live without them.
Today's automobiles come with a variety of extras, from
passenger side air bags to the ubiquitous car alarms.
Entertainment options range from high-end speakers and CD
players to multiple DVD players. The GPS navigation system,
however, forms the bridge between safety and entertainment
features. While they're definitely entertaining, they can also
become a must-have safety net in your travels.
GPS (Global Positioning Satellite) navigation systems can
replace all the maps in your glove compartment and ensure that
you arrive at your destination on time. GPS navigation systems
are equipped with mapping software and can give you driving
directions, show you alternate routes if you're stuck in a
traffic jam, and can help you negotiate a new city. While you're
on the road, a GPS navigation system can also guide you to the
nearest gas stations, restaurants, and other points of interest.
Some GPS navigation systems are built right into a vehicle,
while others are handheld devices that mount on your dashboard.
Although GPS navigation systems are used by everyone from rescue
workers to hikers, if you're using one for driving, it's helpful
to select one that has voice navigation features. The GPS
navigation system will tell you when you're approaching a point
where you need to, for example, turn, and then tell you to make
your turn. This allows you to keep your eyes on the road, where
they belong.
There are many accessories available for GPS navigation systems.
You can, for example, buy software, GPS holders to mount your
system to your dashboard or windshield, memory cards, cigarette
lighter adapters, antennas, and Bluetooth.
When buying a GPS navigation system, you should consider such
factors as screen size and whether you need a color or
monochrome system. Color systems, for example, usually provide
greater detail and better readability, but also use more power.
GPS is sometimes included in handheld computers (PDAs), so if
you're in the market for a PDA, you may consider buying one that
includes GPS.
Another factor to consider is the memory capacity of your GPS
system. If you'd like more than the basic mapping software, you
may want to consider buying a system that has additional memory
capacity, such as space for a removable CompactFlash card. It's
a good investment to buy a navigation system that has voice
prompts, so you won't have to look at the screen while you're
driving.
