I managed to have the Auto Drive Hellas v. 5.00T (EN) working on my Nuvi, I have simply cancelled all maps and then re-installed them from scratch; I suspect something went wrong on my previous installs. First I installed some countries from the City Navigator Europe NT (Greece included) and then Auto Drive Hellas, now I can imput a route to Greece using this map (of course deactivating the City Navigator Europe NT) with latin characters.
