Cell phone GPS works well
O.K., so I don't like asking for directions.
But I don't get lost so often that I need to spend more than $1,000 on a built-in car navigation system to plot my course with global positioning satellites.
Nor am I so directionally challenged that I'd want to spend several hundreds for a portable GPS device that I'd need to lug around every time I park my car.
And while some handheld computers have GPS capabilities, not nearly as many people carry a PDA as the legions who've adopted cell phones as a daily appendage.
That's why the notion of adding GPS navigation to a cell phone, as Nextel has with a service called TeleNav, seems appealing.
And despite some annoyances having little to do with technology, TeleNav performs the most essential task quite well at a fraction of the cost, reading step-by-step directions out loud so you can focus on the road.
Make no mistake. TeleNav is nowhere near as robust as a full-blown GPS system or a portable device.
