Being a "tool girl" (and someone who more often caches using my phone versus a GPSr), I found several alternative solve methods that saved my sanity. I use them depending on which I have immediate access to.
* GeoSphere - In my IOS app, I can Edit > Edit Options > Edit Location to access the coordinates. If you click the sprocket, one of your options is Project Location. TaGeez uses the GCC Calculator for Android.
* If I'm at a computer, I use GSAK. Click the Waypoint menu option and select Project. You can find further instructions in this forum post.
