I currently own a Garmin DriveSmart 55 and wanted to update the maps from "City Navigator Europe NTU 2019.10" to a newer version. I've been able to get hold of the "City Navigator Europe NTU 2024.10.gmap" files however when I try to push the files to the Satnav using Base Camp, The satnav tells me the files are corrupt and cannot be used.

Is there anyway I can get the files to work or do I have to buy a new device?
