hy petrutms,i think u're the only one who can help me.I have the same problem like user mickeulk:when ever i push navi button i get this screen
this happens with or without gps card inserted.
I tried u're update and instructions..nothing happens..the same screen.
however,accidentaly,trying all kinds of updates,i discovered a set of files that were similar to yours(autoupdate folder,NWDTCali.exe and updater.cfg).It seems that this file updater.cfg makes my screen change like this:
It's the only change i've seen for moths.However beside the screen change nothing else happens.No response from touch screen (only a click sound),no progres bar,nothing else happens.It's like the"update"button should be pushed, but there's no way to push it.
