"You could however hear booth languages if you do it like Garmin developers expects the user to do."

I think the developers had much better approach with the "Phrases" part where both language options were provided on the one screen. Much more user friendly than changing language setting in dictionary and then searching for word in unknown language.

Overall though I can see that the GLG could still be a useful tool when travelling in a foreign country. I was thinking maybe 'Commerce' needed POI data from Europe map which I don't have loaded. Interesting though that 'Commerce' problem seems to be a fault in the original package, and is limited to certain models.
