I think the big thing for me, a self-confessed unvergence fan, is having my phone do anything other than manage my comms. i don't even listen to music on my phone, because I don't want it to be interrupted by a call coming in.
Guaranteed, just as I am bulleting towards some major interchange in a foreign country, in the dark, at rush hour, Vodafone will call me with some 'amazing' deal on an upgrade, the sat-nav will crash and then, perhaps, so will I!
So, I agree with the others here who said that a separate sat-nav device, well set-up to my preferences, and giving me premium info like live traffic, is preferable.
Then again, I am in the privileged position of having access to all sorts of expensive sat-nav devices; free sat-nav might be too much of a draw for some...
