Cabasa,
Send a PM to BigBob. He bought an CX9 that was imported to Europe.
From conversations (PMs) with him, it seems like you need two disks to make it work.
1)- a system program disc to load the program
2)- a map disc for #1 to read
Everytime, the battery is disconnected, you need to do the two-steps again. Unlike what we get in USA, both are on the same disc (program + map).
My guess is that no one make such a disc, so the importer somehow figured out a "hack" to make it work. Anyway, that is as much as I can contribute. BigBob can probably help you even more...
