spainisch cards have no details on my garmin Etrex 3O

When i download spainisch maps , they have details visible in basecamp but onece installed on my garmin Etrex30 there are no details visible. I redid the downloads severla times redid the installation on my garmin several times.

someone an idea what I do wrong or miss ?

Maybe this ?

Also note that when you install a map of Spain, it won’t have data for other areas - and hence show nothing when you are not in Spain.
Also make sure that the map is activated (some where in the Settings menu, you can select the map(s) to use).
You could try to switch your Garmin into “Demo” mode and move to some waypoint / address in Spain. If you still see no map, there’s really something wrong.
