Using iPhone maps offline?

I can use my NAVIGON map app offline, but it won't use GPS, just the map, unless you have service.

 

The mobile Maps app downloads map segments as they are needed, so it is out.
Have never tried my Navigon app without a data connection.

 

You can pre-download the location you want with internet connection (free wifi). You will still be able to see the map when you go offline.

 

Yup. Get a nav app with locally stored map data. Navigon is mentioned above. TomTom is another option. This is by no means an exhaustive list.

GPS does not require data. What do you mean "it won't use GPS"? Do you have airplane mode enabled?

 

Do you want navigation or just maps?

If you do not require navigation, download City Maps 2Go Lite.

http://itunes.apple.com/gb/app/city-maps-2go-lite/id408866084?mt=8

In the "Lite" version you'll only be able to load one city of your choice, but it'll be fully cached, no further downloads required.

It's got a great POI database too.

 

GPS will work with it, it will show you your location, but it will not guide you i.e. turn-by-turn directions are absent.

If you want navigation look at Sat Nav 2/Skobbler, it used to be free, now it's like $1.99 or something and you can buy an offline map in it's options for around $3.

 

City Maps 2Go is a commercial app but you won't have to pay for extra maps once you buy the app, with the Lite version, you get the app for free but you will only be able to load one map.

 

Cartographer is a great option. It lets you save any map offline.

 

You're welcome, have a nice trip!
