Dear all,
Garmin Express is challenging me again. I have installed 18GB TopoActive Europe 2025.10 on my 840 recently but now when I connect my 840 to my mac with Garmin Express it is saying that there is an update for the Maps, which is exactly the same version (2025.10). It is also telling me that there is an update for North America 2025.10. Why the heck wants Garmin Express to install these maps? 
Any pointers are much appreciated
