Products like these are particularly well-suited for business professionals who are always on the go, especially if you make sales calls in unfamiliar parts of town. Instead of investing in a standalone GPS device for your car, you can save a significant amount of money by buying a Bluetooth GPS receiver and pairing it with your Bluetooth-capable PDA phone. Something like the Holux GPSlim236 (which I’ve only heard good things about) should work perfectly with the newly announced HTC TyTN from Rogers Wireless, the HTC P4000 from Telus Mobility, and possibly even the Motorola Q that has everyone raving.

The main advantage to buying a Bluetooth GPS receiver rather than a standalone device is price. A decently equipped standalone unit will cost you around $300 or so, whereas the Holux GPSlim236 can be had for around $100. There’s a variety of GPS software out there for you to consider, depending on the operating system of your PDA phone. Windows Mobile devices are particularly well supported.

Stop fumbling with paper maps and jump into the 21st century. GPS maps are definitely the way to go (and the best way to not get lost).
