I tried to unlock WindowsCe but one mistake from me...line Launch10 -shell.exe changed to -explorer.exe and now nav just goes to Arival logo and can't connect on PC (off course)...so is anybody have update FW for these navi or maybe just a name of update .exe?
Btw..on official page update not available and answer from Germany is:
Dear Sir,

if your navi starts with the a-rival logo on a white screen and stops there,
you should send your navi to us. There is no other way, because we can't
give you the firmware.

mit freundlichen Grüßen / Best regards
