For all you people who says Nuvi's can't be used, I used a Nuvi 350 for over 600 finds before I got a Oregon 400t. Just select the pedestrian mode and off-road and you should be fine. and you can also load the Nuvi with Caches and you will get a alarm when you are riding down the road and a cache is near, then all you need to do is select the cache and go find it.
