If you'VE use a Global Positioning System, or G.P.S., to discover where you are, you'll appreciate the new iQue 3600, which integrates G.P.S. technology on a palmtop device.

The result is a tiny handheld that doesn't just tell you where you are, but can help you get your load to where it needs to go.

The iQue 3600 runs on the Palm 5.2.1 operating system and synchronizes its calendar, address book and to-do list with a Windows PC.

How it Works

Flipping out the antenna on the iQue activates the G.P.S. system. The iQue hunts for satellite signals, then shows you a map of your current location.

That's where most G.P.S. systems stop. But the iQue can help navigate in unknown cities or find the nearest gas station, truckstop or restaurants.

The iQue also works like the navigation systems built into the dashboards of some expensive cars, giving you turn-by-turn directions to a destination you enter. A built-in speaker projects a woman's voice announcing upcoming turns, so you don't have to take your eyes off the road.

You can buy a "car kit" with the iQue that would work in your big rig. It comes with a pedestal to hold the iQue upright so you can see it, and a cigarette-lighter charger, so the batteries don't run down and leave you lost.

The iQue is made by Garmin International Inc. and has a $589 suggested retail. Find out more at www.garmin.com.
