TomTom app for iphone.

Encantador

Does it constantly use the internet to download data?

If it does, it would be pretty much useless abroad because of the data charges.

As far as I know it works offline. It can use the phone signal to improve GPS accuracy, I believe, but it will work on just the internal GPS.

What she said ^

The Western Europe one takes up 1.7GB so make sure you have space on your phone. But it's a great satnav app.

The TomTom app for the iPhone does not download map data. There is a feature called MapShare that provides access to community-sourced map changes, but this is purely optional.

ALL of the map data is stored on the device.

The iPhone GPS does rely on a cell signal to calculate location, but you can purchase a TomTom car cradle that boosts the GPS signal.

If you subscribe to HD Traffic, then it would use some data bandwidth to get its updates.

There used to be a fudge for my old Nokia N82 running TomTom.

It was a bluetooth app which fooled the tomtom software into thinking the inbuild GPS was in fact, an external TomTom GPS Receiver.

That was years ago, surely some boffin has managed to fudge the iPhone version to save having a stupid external GPS as well as the perfectly capable internal one.

But then again, it is an Apple device so maybe not.

this is wrong, the iphone does not rely or require a mobile signal in-order to use GPS,
you (like many others in the world) are confusing A-GPS and GPS, A-GPS uses the data network for faster GPS lock on, GPS only just uses the satellites and inbuilt receiver therefore it may take a 1-5 minuets to lock on

therefore if you want to use the tomtom app without a data connection then you can (either turn off data in settings or use airplane mode), you definitely don't have to buy the tomtom dock in-order to use the app (which doesn't boost the GPS signal, it just has a more sensitive receiver allowing slightly better signal retention, or allows the ipod touch (which doesn't have GPS) to have GPS)

no 'hack' required, see above.

Either you haven't grasped my point, or I haven't grasped iPhones (which is possible as I have never had one).

On the Nokia, by default Tomtom will NOT accept the internal GPS receiver. It is impossible to select it from the menus. You have to purchase a seperate bluetooth GPS receiver for the application to function (receive positioning data).

I'm assuming iPhones are the same - but alas, I have never owned one so am not sure.

The hack was to make the phone, ergo TomTom, think the internal GPS receiver built into the phone was actually an External Bluetooth receiver. At which point Tomtom was happy.

Bad assumption, the internal GPS is in fact the only supported GPS device, TomTom for the iPhone has no configuration option for external GPS devices.
