Bluetooth gps navigation became rather popular these days. In fact,
what could be better than using your pocket pc, palm pda or
bluetooth mobile phone for knowing where you are or finding the
direction to a certain location? So today, for the mobile phone
navigation, you need a bluetooth phone like the nokia 6600, 6630,
6670 and 6680 while the requirement for the pda is for it to be
Essentially all you need for your complete mobile satellite navigation
is your pda or mobile phone, a bluetooth gps receiver, the satellite
navigation software which usually comes in or with a memory card
also containing the digital maps of your chosen country or region, a
car charger for the pda or phone (you don't want to run out of power
in the middle of nowhere) and finally a pda or phone holder to hold
your precious phone/pda in place while driving. As for the navigation
software, probably the best solution is the TomTom Navigation
software. A lot of people ask if you require a subscription, the short
answer is NO except if you want to take up a traffic subscription.
Incar dedicated navigation systems can be very expensive. So if you
have a compatible mobile phone or pda, buying a bluetooth gps
receiver and navigation software can be a cheaper alternative.
There are other advantages like being able to move it from one
vehicle to another, like when renting a car for example. Not to
mention navigation while walking.
But before taking an example, let's first make sure we know what
the bluetooth technology is about. In general, there are lots of
different ways that electronic devices can connect to one another:
component cables, electrical wires, ethernet cables, WiFi, infrared
signals and so on. When you use computers, entertainment systems
or telephones, the various pieces and parts of the systems make up
a community of electronic devices. These devices communicate with
each other using a variety of wires, cables, radio signals and
infrared light beams, and an even greater variety of connectors,
plugs and protocols.
The art of connecting things is becoming more and more complex
every day. The new method of connecting devices is the Bluetooth.
Bluetooth can streamline the process. A Bluetooth connection is
wireless and automatic, and it has a number of interesting features
that can simplify our daily lives. Bluetooth is a specification for the
use of low-power radio communications to wirelessly link phones,
computers and other network devices over short distances. The
name "Bluetooth" is borrowed from Harald Bluetooth, a king in
Denmark more than 1,000 years ago.
Bluetooth technology was designed primarily to support simple
wireless networking of personal consumer devices and peripherals,
including cell phones, PDAs, and wireless headsets. Wireless signals
transmitted with Bluetooth cover short distances, typically up to 30
feet (10 meters). Bluetooth devices generally communicate at less
than 1 Mbps.
One of the most popular bluetooth gps navigation devices is TomTom
Navigator USA Bluetooth GPS. This is probably the best in-car, turn-
by-turn navigational system for handheld devices. It has excellent
maps, 3D views, and an intuitive and well-designed interface. The
integrated package includes the compact Bluetooth GPS receiver, a
cradle, power cables and a car mounting kit, as well as the
navigation software and maps on CDs.
It's the interface that really makes this product stand out. The
screens are focused, omitting any extraneous details; whether a
navigation map or application screen, everything is legible - an often
overlooked necessity for PDA navigation. And rather than having to
use a stylus or small drop-down menu, TomTom provides large on-
screen buttons that can easily be selected with a finger.
The TomTom PDA software has an impressive 3D mapping feature.
Most in-car GPS systems display the current location as a small
moving dot on a flat map, but TomTom's software provides a 3D
view of the street. A conventional map view lets the driver zoom in
or out and provides overviews that range from the entire state
down to street level.
Unlike other companies that produce handheld GPS products,
TomTom treats the PC solely as a conduit for setup, installation and
transferring of maps to your Pocket PC. You don't preview or edit
maps on the PC before transferring them to the handheld. Instead
TomTom provides a collection of more than 180 predetermined state
and regional maps on CD ready for download. These map files
range in size from 2MB for the state of Rhode Island to 33MB for
New York City and 60MB for California. Regional selections can
increase the state map requirements to 160MB. That said, you'll
need a 128MB or 256MB MMC or SD card if you plan on taking maps
of large states or multiple states with you on your Pocket PC.
Planning a trip is a pleasure as well. Just like most bluetooth gps
navigation devices, TomTom lets you navigate to a saved favorite
point of interest in the database, or to an address of your choice.
When you type in your city or street names, the application lists
possible matches from the database, which is a great time-saver.
When selecting the destination house number, TomTom actually
provides a list with cross streets, a feature that came in handy more
than once; the cross-street list is especially useful if you are not sure
about the exact address.
