using palm pilot as a gps

I use a Pocket PC HP Ipaq 2210 with a Garmin Etrex GPS running OziCE. It's a great little setup and in the car and boat I use a combined data/power cable which means both devices are powered from the cigarette lighter.

As to how useful it is has a lot to do with the quality of the maps you are using. There are still times when you can't beat the old paper map. However, you can still use the GPS to get an accurate fix which you can plot on the paper map.

Darryle, I recently moved across to Pocket Pc, but you will find some relevant info for Palm on these pages
