Just bought a Garmin Venture HC and was surprised to find out the base map is junk. We started geocaching with a cheap Lowrance iFinder Go2 that has a great base map. I was hoping the Garmin would be much better. I checked out the Garmin site and for an additional $129 I can get a map as good as the $20 ifinder came with for free. I saw some posts here about free base maps. So, what do you guys recommend. If you say give Garmin more money this baby is going on ebay. Thanks.
