This allows you to connect a Deluo GPS receiver to the PDA.
If you REALLY want to get something that is fantastic, you'll want to get a Compact Flash GPS receiver, that's what I'm looking forward to.
Here are a few:
Semsons Holux GPS

And the Pretec CF GPS:
Normal ($209):

Low Power ($169):

There's this unit which is $300 CDN and I know of a person who purchased it and was fairly happy:

What you will need to do is, once you purchase the unit, you will need to get a Map program like Microsoft Pocket Streets (don't, stay away unless you don't want to spend money on something really good, although this does come free on the Axim CD, I believe) or
Mapopolis (I HIGHLY recommend this program. It is brilliant in design as well as execution, and can be used with or without a GPS receiver. It has saved my you-know-what many times).
Once you have the map program and the GPS device connected, you're set and they will interact together to map out where you need to go, and the steps to get there.
Hope that answers your questions! If not, let me know.
