GeoCaching with Garmin Nuvi 350

By default, my Nuvi 350 came with an old version of the firmware on it. Upgrade the Nuvi Firmware. It is both free and easy with a computer (you have one of those right?.

Once you have the firmware upgrade, you can add GPS coordinates manually - In the "Where To?" menu, scroll to the bottom for the coordinates button.

You can also add coordinates by copying gpx files to the Nuvi using the Custom POI loader from Garmin. Upgrade your geocaching membership and get pocket queries - you can load 500 caches at a time onto your Nuvi and they will be searchable (fun to do if travelling).

The Nuvi has over a GB of onboard flash, so you could load a lot of caches before running into space issues. Unfortunately there doesn't seem to be a way to get the cache descriptions to appear on the nuvi. I've done this with a palm separately, but it is annoying.

Once you are near a cache, change your Navigation settings to Off-Road and Pedestrian. When you are nearly on top of it, go to the skyview mode (just tapping on the screen when it is in 3d mode will do this) and zoom in as far as you can. This appears to be the best way to get high resolution on your cache. It isn't perfect, but it works plenty well enough.
