Compare Google Navigation on Android, to TomTom on iOS. Navigation is free, works perfectly, and even goes so far as to include a "Car Mode" for docking your phone in your car.

TomTom costs, at last check, $95NZD. I've not bothered trying it.

I do believe TomTom has data for offline use, unlike Google Navigation.

(I have iOS tomtom for western Europe) Also, it has voices in many languages. So it will still work when you're out of coverage/country.

Remember, 99% of the land surface has crap/non-existant 2G/3G/4G coverage.

I think the difference would be that TomTom supplies it's own maps in the App, whereas Google Navigation probably downloads the tiles/street view as you go.

This can make a world of difference when travelling abroad when you can't be bothered getting a local data plan.

I definitely use GPS navigation more often when travelling than when in my home country.
