iPhone Sat Nav

[RosscoPCole]

I want a free sat nav for my iPhone 4
that I can use in Belgium without receiving a huge bill for data roaming.

Is there such an app which I can use with data roaming switched off?

Please excuse my ignorance.

I use Skobbler on my iphone in those circumstances.

Not as good as Google Maps but perfectly adaquate to avoid roaming charges or when out in the sticks with no 3G coverage.

About 3 quid for the app and £1 each to download map for a single country or £10 for the whole world.

Im up and down the country all week and never been let down yet with google maps.

Have you tried using Google Maps with the cellular data on your phone turned off, which is what the OP wants to do to avoid roaming charges while he's in Belgium ?
