I've read the solutions in the forum, of course.
I'm using a windows laptop with the latest version of itunes, Both that laptop and the old desktop instantly freeze their explorer when you connect the ipod. the second you unplug the ipod all goes on normal.
The ipod does have a rest setting's choise under the settings, but no choise to reset all. (tried that several times, only the settings for language etc are reset.
Problem is in the database that registers the files. In my car it stil plays most of the music, but it shows double names and those i have to skip manually.
