While navigating to a cache, you can add custom waypoints. Add a new waypoint, and the compass immediately points to it, and coordinates are displayed. At least that's what happens on iPhone. I tried to check it on my Droid just now, and cache info is not loading, so I can't verify the exact same thing happens on Android. But I know you can add waypoints and navigate to them on the Official App on both types of phones.
Thanks for pointing this out- I just tried it and it works on my iPhone
