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 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.
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.
