I have an old Garmin Etrex Vista Cx that was given to me about 4 years ago. I started using it for Geocaching, and then, life got in the way. It went into a drawer and hasn't been used since. I want to get back to Geocaching, but I remembered being frustrated by the lousy map that came on the thing. I'd like to put on a better map system. Which would be better - a TOPO map or a city navigator map? I know...I don't need something more than what's on there to do geocaching in general, but it would be nice to have something at least a bit more detailed. Suggestions? Btw, I live in the Atlanta suburban area. So, I have plenty of city around me...but I also get out for hiking and trails, too, up in the northern part of the state. Thanks for your help!
