Now I know that it wasn't the original question, and I'm not trying you to convince to using Garmin Drive. But...
If you say "Changed the menu structure" then I'm almost certain that you allowed to use 'Garmin Explore' when installing Garmin Drive, or you have enabled that later on. If you dont allow Garmin Explore then Garmin Drive and the XT behave perfectly, and you still can use Wireless transfer, weather info etc.
This is a (long) thread on how to install Garmin Drive without enabling Garmin Explore
