The software is excellent; no question. But the way how the manufacturer protects against piracy is to only be described as highly customer-unfriendly. Background is as follows: I use my PDA in a 8 GB card, for example, I use a full German version of Wikipedia (size approximately 2 GB) and various other software. Even with the offered 4 GB card with the navigation software would not be sufficient to install "my" software space. So would remain just the way the. A map for navigation, the other to use for anything else So: Permanent map change. And that can only be assessed with a maximum of a star for me this software.
