Thanks Boki_Srb for the reply, but my skills are not so good that i can re-programm the flashdisk inside the navi unit.
(i am a 64 year pensionado, my computer-knowledge is autodidactic....)
I am scared to brick the unit, i have read it before......
The unit is now working fine, i only want map-updates, but now I think I ask them for a birthday-present....

THANKS!!!!
