Question: Have you updated the maps since you got the unit, especially the European map? If NOT, the Europe map will be on your unit and all you need to do is Manage Maps-->Switch map and select Europe as the map.
That said, if you do so while in the States, you won't be able to Navigate to an address since the gps still puts you on this side of the ocean. But, you can do Advance Planning from A to B and choose France in the city screen for the Starting point prior to selecting the city. And then also select the Destination city.
You can also establish favourites on the map (France) using the lat/long if you have the information by Manage Favourites, Add Favourites and one option will be lat/long.
You can get such info from Google maps, for example and then transfer to the unit in this screen. Just make sure the format for the gps info in the unit matches that in Google by (in the unit) tapping the satellite bars and in the next screen, click on 'configure'. You'll see a screen with 3 ways to display the gps lat/long info. Just select the appropriate one.
I do not know whether Postal Code search works in France.
