I admit I'm totally ignorant about using a mobile as a GPS.
a friend is going to england and will be driving and wants a GPS
How can she use my old G3 as a GPS and it not cost her anything while using it?
does it have to cost? do you need a sim installed? thanks
You don't need a SIM during use, and I recommend copilot GPS using UK and Ireland maps, as that is what I used when I lived there.
Just make sure you install, configure and run it up the first time while online in AU, unless they are going to have Internet access in the UK (plenty of coffee shops and cafes offer it for free there).
