My wife, kids and I are new to Geocaching. We are currently using our Nuvi for caching. I want to buy her a new GPS for her Birthday. I want it to give driving directions if needed like her Nuvi, but I also want it for caching..such as entering Long/Lat coordinates and able to access geocaching.com for paperless geocaching. I was looking at the Garmin eTrex 20......Good/Bad???? Thank you..also, does it have voice directions for driving?
