Program help on Etrex Venture & Cordinate Interpretations


New member
Morning Folks;
We bought a Garmin Etrex Venture HC to take with us and navigate in southern AZ prospecting and nugget hunting;
The problems we have are first we got the topo US 100K program and it is totally worthless and way to dificult to operate with or in or however you would word that. The screens on the computer even are about useless; Is there a good program that one can install on the computer and download into the GPS unit that is user friendly and more detailed; preferabllly one that is a internet download????
Second it comes to my memory there are two types of cordinates #s that one can run into??? I seem to remember having some cordinates for a location and using google earth to find it from my gps cordinates put me in a different place and was told one used one type and the other used another type system? Was I dreaming or is this fact and can someone explain??
Sorry for being so computer challenged but the wife is pretty good with computer stuff and this is driving us both crazy we would appreciate any references or anything to get our $ worth out of this gps .
Thanks very much for the help
There are more than 2 co-ordinate systems. It's too much to explain here so... go to and read the basics.

eTrex can not be loaded with other "programs". You can find other maps for it but they have to be compatible with the Garmin MapSource and your receiver so, better learn how to use it. For US, you can buy more detailed topos from Garmin.

I think maybe my question was not stated correct; What were wanting to find is a more detailed map to use in conjunction with the etrax. The topo us 100k seems to be very poor quality details?? Is such avaliable?

We will go to the other page and learn about the more details of operation also; thanks;
Are you looking for printed maps or maps that you can load to your receiver? In any case, both types are available with much more detail and accuracy than 1:100.000 scale maps.
For computer images, just do a search for USGS 1:24,000 topographic quads - you should be able to find them free on the net or you can buy printed versions of these. They are very decent and detailed.
