Ukraine Train,
There are several software packages out there that will display your location on a map dynamically. If you already have Garmin's MapQuest software for loading maps into your GPS you can hook it up to your laptop, fire up MapQuest and have it detect your GPS. Bingo, you're on the laptop's map instead of the dinky GPS screen. That's what I have used with my Rino 120.
Most GPS receivers and mapping programs can be made to work together, though there are different conventions for the data stream.
