You can connect the 2720 to your PC using USB mode (you're prompted to select USB or Garmin mode when the unit makes its initial connection to your PC).
At that point you can erase whatever is on the 2GB flash module, that is, the City Navigator US version street level maps (approx. 1.2GB).
You will not be able to erase the US base map, AFAICT.
You should now be able to load the Euro street level maps.
