Stinks, doesn't it. My caching GPS doesn't have street maps in it. I do have a car GPS. I usually print out
the google maps (which also doesn't work) and at a glance I can get a feel for where the caches are. Without the paper print out, or even looking at the PC, it's very tough to figure out where something is and how to get there. My car GPS can do directions but entering N + W for a cache into it, to see where it is, is a pain, doing one a time
What you can do, is click the map on the caches main page with the description of the cache, but that's only good for one cache at a time.
