GeoCaching Problems

How do i do it on the Monterra ?

If find the Monterra and garmin software like windows - pretty dumb and useless - i like macs that are easy and work

I can't find anywhere in base camp (OS X) to do geocaching

There is a geocache app on the monterra that has nothing in it

SO i donloaded a gpx file from geocache - and this displays on basecamp - but even after transferring to the device (monterra) i am still unable to see any geocaches in the geocache app or on the os maps ?!!!

Its totally ridiculous and very un user friendly !

All help appreciated
