Query: Upgrade and Tech Support are horrible.

I bought a European model with level 4 software and it works ok in Europe. Forget about upgrading. Forget about expanding to be able to use it in North America. You will spend as much as you would for a new one.Tech support is terrible. The rep did not understand the product, did not speak english very well, and did not even understand my question.Next time, no Magellan.
