About this you quoted: "When the 'SW Ver' page shows, press 'Next'/lower RH corner until you reach a page headed 'Version Information' ....". In full explanation, if the word 'Next' isn't shown (as on the colored screens) just keep pressing the lower RH corner. On modern device you need to go thru many screens to reach the Version Information screen.

Hi
everything is good now
I was wrong, I dragged the .gcd on the open window of Webupdater while it was enough to drag the .gcd on the icon of Webudater
thanks again

I do not think that this model is patchabile.
Its HWID is not recognized by the Patching Tools.
The Original GDC is not found either

I can try but I don't guarantee anything

Has anyone tried copying the gmapsupp.img to the garmin folder on the SD card Garmin and got it to work?

I have a Nuvi 66 LMT and using a micro SD card to store the maps. Just trying to find a European or UK map file I can copy into the Garmin folder, please.
