Have you ever tried to find your way across town (or across the country) using an old-fashioned road map? The only thing trickier than deciphering the directions, is figuring out how to re-fold the map! Today's travelers are finding it much easier to find their way with GPS receivers, PDA devices and Bluetooth technology.

The need for traditional maps and navigational devices has virtually disappeared since GPS devices hit the market. Now, travelers can simply refer to the GPS screen to access clear direction on where they need 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.

For increased convenience and usefulness, GPS receivers are often paired with other mobile devices. The PDA is one of the most popular mobile products used for this purpose. With a colored screen that can clearly display maps, and some hard drive space for map storage, PDAs are wonderful partners to GPS receivers. Consider the small size and light weight of a PDA as compared to other options like notebook and laptop computers, and it's easy to see why PDAs have become the first choice of modern navigators.

Integration poses a problem with using a PDA with a GPS receiver. Most PDAs are connected to GPS receivers with either a CompactFlash (CF) card, or conventional USB wires. The size of the GPS, added to the size of the PDA, plus a CF can create a bulky and cumbersome system. Using wires, on the other hand, can be inconvenient and actually limit the usability of your navigation device. Many people are finding the best solution to the problem is through Bluetooth technology.

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 GPS Receivers

Bluetooth GPS receivers are electronic devices that use wireless technology or Bluetooth electronics to transmit GPS data. This data is transmitted to a second mobile device that is capable of handling the same technology. In other words, a Bluetooth GPS receiver can send data to a PDA, provided that PDA is also equipped with built-in 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 Connection

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.

Added Storage

If you are using Bluetooth technology to transmit data, you'll have no need to plug in a CompactFlash card. The empty CF slot, therefore, can be used as a storage space for software or maps to further optimize the results of your GPS.

Bluetooth GPS manufacturers will offer further benefits with their equipment. For example, many Bluetooth GPS receivers feature a POI (points of interest) database, pre-stored maps and route re-calculation function.
