But also tell us some details of your device.

Does it have a sdcard slot? Can you make contact with the device from your computer?

?
sometimes you have to repeat it 2 or 3 times
Was the navecore patched? Where did you find it?

Peter

Tried clear flash 3 times, no result.
I found the navcore online after the wnro, yes is patched.
Do i have to try another unpatched NC for a "fresh" start? What can you recommand?

edit: found the nc on gpspower.net.

You can try to empty the memory of the device (except the Benelux-map) and make contact with TomTomhome.
Often TomTomHome offers a new navcore than. Sometimes have to repeate it more times because TTHome offers a very old navcore (7.x) first.
Than you repeat asking for updates till you get a 9.x navcore.
If this is succesfull, you have to patch the navcore youself because it is than a official one.
By the way I prefer
