Here a more detail about the Samsung G810 . The software for GPS navigation is very similar to the one on i550 and i560 and Google Maps 2.0 comes pre-installed and work with the on board GPS receiver.

It has a dedicated button for activating the GPS software which in this case is Navigon 6.27. Like Nokia, with Samsung all you get is a two week trial version after which you’ll have to pay about 60 € for route calculations and voice guidance.

You can check out this extended review of G810 which talks about all the navigation software in detail and provides photos taken with the 5MP camera and 3x optical zoom.
