Hi Kunix, firts of all many thanks for the reply, amazing how people can help each other.
I used the file file Zumo_update220.rgn
Processing C:\Garmin Download map 220\Nieuwe map\Zumo_220update.rgn
This is a RGN file.
Patchable HWIDs: 723
*Processing HWID 723
Processing OK :)
after doing this I can connect back my Nuvi to my pc
but when turning on I see Garmin on the screen and than turns off
