@Cman, Using a Nav. app and GPS does NOT use Any Data allowance. As long as you update your phone (apps, etc) by cable to your computer, or via WiFi you will never need Data on your phone. You certainly do not need data to use a Nav App. You only need Data *if* you want to connect to say get emails, use google on the road, Facebook, Crema Chat, etc, etc, etc. Data is a switch on your phone you simply turn off, or on. The big Caveat is that if you do not pay extra for a dedicated data pack and you turn Data on you most definitely will be slugged exhorbetant rates. For example I have about 8 mobiles on my Master Builders Plan. I have a couple of 'extinct' $10- casual plans in that as well. I had cause to use one of the spare numbers with no Data and simply connecting to check emails 4 times over a month for 10 mins each time resulted in a WAP charge of $475- for a total of 45 mins Data for the month. Nasty s$&t right there. I can't be bothered explaining the whole story, but it was because Master Builders "forgot" to charge $15- for a casual Data Pack, for the month. The WAP fee will be credited because it was their stuff up, but take it as a warning. You don't *need* Data, but don't use it unless you have bought a Data allowance *before* you switch it on. Good Luck, there's only about 5 Gabillion phones to pick from..... Then there's at least a couple of dozen Nav App's. Ranging from Free to $400- odd for 'MudMaps' which is a full featured off road touring App. Very similar to Hema's off road setup. Personally I like and use Sygic, but as @UNM pointed out, some (many) people hate it. It is not perfect and they all have a learning curve, there is no perfect solution. I think Sygic is around $40-, Tom Tom (app) is around $99- and there is an option at every price point up and down from there.... Good Luck.....
