Thanks Boki_Srb,
I downloaded Notepad++ to use in the future.

I am trying to update a Kenwood DNX6180 and it seems all I need now is the map image file.
Since DNX6180 is not supported anymore, Garmin won't let me download the map image I paid for(City Navigator North America NT PART NUMBER 010-D0743-00), to be used with this device.

I do have a Nuvi200 that is functional, and it would let me download the map image that I paid for(City Navigator North America NT PART NUMBER 010-D0743-00), under this device in Garmin Express
So my question is, would downloading it that way allow me to get the map image file and then use it to update my DNX6180?
