had a really good play with the nav today, as the test drive car I borrowed had it.
must say it takes some getting used to compared to the old nav, the voice is more American and I couldn't figure out how to make her loud enough to hear over the stereo

Also the only way I could get the map to show was to select a destination, and then cancel it, so not as easy to navigate. I'm also not convinced that the new stylish black back ground is as visibly easy to use as the current mapping, yes it might look more attractive, but function should be more important IMO
