Is it a standard, or wide nuvi? the standards are limited in their ability to be used for caching, as you can't look at your position real-time. That being said, if you're willing to click back and forth between a couple of screens, it can be used.
The wide screens, on the other hand, will display the satellite screen while you're looking. I know of one person who has a 200, we have a 250 which has the same limitations, and of course howlingmoon has hers (not sure which model) which she's used to make >500 finds.
As howlingmoon says, there is a GSAK macro that used with your Garmin POI loader will upload them to the NUVI.
