But a great cheap navigation tool I came across is an app called Avenza Maps. The App is free for Android & iPhone. You can get free Geosurvey Australia (or whatever they're called) maps for it and then you have a free navigation tool. You can also buy most maps from their store to use with it as well. I've bought a Hema and a Westprint for it. It works very well.
As a price example, I used it when I recently crossed the Simpson, I used Hema's Simpson Desert 500K map. All up I had a navigation tool that cost $11.95.
Very hard to go past if you'd like a GPS navigation aid and you don't have much $$$$ to spend on one. If I were starting out and had no GPS navy stuff, I'd get a cheapish Android tablet with GPS capabilities, throw that app on it and away you go.
