Hello Luc,
well, I think the behaviour of my device is identical.
I switch the language to Dutch, the device restarts, I go to Extras-Travel Guide and I land on a page with five selection boxes where I can not select anything. (Reisgids, Selecteer etc).
Once I have clicked on the "Selecteer" fields, the device is blocked and I have to switch it off to make it work again.
I suppose that they did not translate the travel guide into Dutch.
Regards,
Peter
