Thinking about buying a better phone - The Samsung galaxy ace seems to be reasonably suitable.
I was thinking a device like that would be handy if it handled GPS functionality as well.

Looks like in Aussie they get Navigon maps for AU and NZ pre installed - this seems to be pretty much a full GPS solution - It seems to come already installed on the SD card.

As we dont seem to have access to that here (feel free to prove me wrong), I guess I would be looking at google maps.

Is anyone running google maps navigation on an android phone (like the samsung galaxy ace), and especially how does the voice guidance  work ok. I think its pretty crucial to have spoken directions especially if driving.

Anyone got any experiences?
