Navigation is yes -- Does Android come with free navigation in non-US contries?

And it has voice -- Talking GPS software for Android?

But do you need a data plan?

GPS in most of the smartphones are aGPS.

"Standalone" or "Autonomous" GPS operation uses radio signals from satellites alone. A-GPS additionally uses network resources to locate and utilize the satellites in poor signal conditions.

So in my phone HTC Desire, it automatically updates some GPS system file via Internet so GPS lookup can happen quickly. However, in normal GPS operation it won't require Internet so it doesn't require a data plan.

    On most (if not all) Android devices aGPS can be switched off to eliminate mobile data use on pure GPS lookups. E.g. in 4.0: Settings -> Location services -> Google's location service or in 2.1-2.3: Settings -> Location & security settings -> Use wireless networks – aleksikallio Mar 05 '12 at 10:04
