GPS and PDA Bring TLC to Your Travels

Traveling used to mean packing along detailed and illegible maps and compasses of questionable reliability. Given the number of times travelers had to stop and pull over to check a map, it's a wonder that we ever traveled at all! These days, modern travelers can easily find their way with a small hand held wonder called a GPS receiver.

Every since GPS became widely available on the market the need for maps and large navigational devices became redundant. Today's traveler can refer to the tiny computer screen on the GPS receiver to find exactly where to go.

GPS receivers are small electronic devices that work by calculating your precise location on earth. This location is found by decoding signals received from satellites in outer space. Using additional electronics and software, it's then possible for the GPS to pinpoint an exact location on a map. This incredible technology is available at a relatively small price.

When paired with other mobile communication devices, such as PDAs, a GPS unit becomes even more useful. A PDA is a popular consumer communication product that combines a cellular phone with an organizer and Internet access. PDAs have hard drive space that makes them the perfect companions to GPS units. This hard drive space can be used for storing maps, and the colored screens are ideal for displaying maps. With their small size, it's easy to see why so many travelers choose to use PDAs over laptop computers and other bulkier options.

There is sometimes a problem with the integration of GPS receivers with PDAs. Connection between the two units is usually made using either conventional USB wires, or a CompactFlash (CF) CARD. The size of the GPS and PDA units together, and added to the added bulk of the CF card, can create a cumbersome traveler's tool. On the other hand, using USB wires is inconvenient and limits the overall usability of the navigation device. Many people, therefore, are turning to Bluetooth technology as the perfect traveler's companion.

Rescued by Bluetooth

Bluetooth wireless technology has become the open standard for wireless communication. Using Bluetooth technology, two electronic devices are able to communicate with each other, sending a receiving signals and transferring data, from up to ten meters away. The beauty of this technology is that the information is transmitted completely wire-free.

Bluetooth with GPS Receivers

A Bluetooth GPS receiver is an electronic device that uses wireless technology (namely, Bluetooth electronics) to transmit GPS data. The data is transmitted to a second wireless device, such as a PDA, that is capable of handling the technology. For example, a GPS receiver can wirelessly transmit data to a PDA handset, but only if they are both enabled with Bluetooth capabilities.

There are many advantages to using Bluetooth GPS receivers with compatible PDAs for data transmission, rather than using CompactFlash or USB wires:

Wireless Convenience

Without wires to tie them down, you are free to position your GPS receiver and PDA device where it's most convenient for you. Many travelers choose to place the GPS on the dashboard, allowing it to maintain a clear connection with satellites in the sky. The PDA is best mounted right in front of the driver, where he or she can clearly see the directions on the screen. With Bluetooth technology there are no wires to limit the convenience or obstruct your view of the screen.

CompactFlash Slot Space

Using a Bluetooth GPS with a PDA means that there is no use for a CompactFlash. The empty CompactFlash slot can then be used as a storage space for maps or software to optimize the navigation of your GPS.

Many travelers are able to get even greater benefits from their GPS receivers. Some units come with handy companion features like pre-stored maps, route re-calculation (perfect in the case of road detours) and POI (points of interest) databases that show you popular tourist attractions en route.

Shop around to learn as much as you can, and compare models to find the one that suits you best. Your GPS will likely soon become a trusted travel companion.
