Did all the changes, if not nothing would have worked ... as other settings are given. Tried old versions, new versions - even different scetches. Nothing.
Closing the thread here as this is hardware service.
tried it on a old machine with arduino 1.0.1 and see there it worked. Was with Kit #2.
Next problem, bought also the Kit #3 (different car). There compiling and upload worked fine now but the 3.2 disp seems to be demaged. Just some stripes and backlight.
