I want a GPS with the following features for use in my Jeep. I don't need features like Lane Directions or Traffic Conditions designed for city driving. I don't mind having them if the GPS will work for Off-Road use.
o Ability to leave Tracks (“bread crumbs) as well as upload and download Tracks
o Ability to download detailed Topo Maps or “Customized Maps
o Ability to enter Waypoint by entering coordinates manually.
o Large memory or standard memory cards.
o Large, Color, easy readable screen.
o Easy to manipulate features while driving.
o Ability to attach to car’s 12v system for power.
o Both internal batteries and ability to use car’s 12v power. So can be used outside the vehicle too.
o Ability to use Routes and Automatic Routing.
Unfortunately Garmin's website doesn't indicate all the features and their User Manual is also not very helpful in determining available features.
