I am guessing that it is on the list of things to work on once NavCore 7 is available for all platforms. Those of you who already have version 7 are lucky since you get all the new features. For those of us with PDAs, we are still stuck with Navigator 6, Tomtom Home 1.5(which does not support the Google Maps integration), and no Map Share, even for those of us who have updated our maps to 675(the latest version available for those with Navigator 6).
It may be the feature will show up in 2008 as well, but as I said, there are "more important" features that will be added before that one.
Since Google Maps DOES work with Home 2.1, if you know you will be going somewhere before you leave, you can use Google Maps on your PC to find where you are going, and then send it to your GPS(it goes to Tomtom Home, which will then send the address to your Tomtom device).
Another solution is that if you know a store that is at that particular place, you can navigate to that POI based on the distance. The downloadable POIs for "retail stores" come in handy for that. It's not as good as having a category for mall and such, but it's a thought for you.
Europe is a different place, and individual towns are more distinct locations, unlike how things are here in the USA where towns just flow together, and the official location/city/town where a given street is may not match the area that street is in(like any street listed under Napeague, NY, which will either be considered Amagansett, or Montauk by most people due to there being no Napeague, NY post office.)
