Installing Topo Pro maps?

How much extra room does it say you need?

It doesn't say, but I searched around the net and the Topo Pro map might need 2.6BG of space and there is 1.47GB of free space on the F5x with the factory supplied maps installed. 

i am not 100% shure, but as a read somewhere, the cycle and the topo-active map are the same. 

Best way i think, is to copy for example the cycle map with all the lizenz files to a computer and the delete it from the watch

This seems like an interesting idea. I would need to figure out the naming schema that garmin is using that I will delete the correct file.

As far as topo-active and cycle maps being the same, at first glance (using BaseCamp) it seems to be the same. Having said that, I have seen reports where car navigation works only with topo maps enabled and fails with basicle maps enabled. Hard to tell if they are identical or not.

i think in basecamp (don't use it) you can right click on the map properties and it gives you the file-name to the map name. car navigation should works with topo-active maps, anyway it does not work on the 2019_10 version of the maps) . don't know about the cycle maps.

I have the same Topo pro 4. You can actually remove from watch either south - west topo or sout-west cycling maps because those are not needed in Finland. Check from basecamp what are the file names that you can remove.

Thank you for the advice! The problem I'm having is that I can't find the file names on BaseCamp. I'm using the latest Mac OS version of the BaseCamp.

I can find the list of the maps and when I click the "Revel in Finder" (same as Show in File Explorer on Windows), the Finder window only shows me the Root folder of the watch, which contains the Garmin folder. So at the moment, I've yet to figure out how to delete the cycling maps that should free 4GB from my watch.

But in principle it comes down to the point that we need a more elegant map installation mechanism to decide on our own which parts of the maps are to be installed on the device when filesize does matter. 

- display device map files in app (garmin express or explore )

- customization of device map files (at least switch on/off complete map types (cyclemap..) and regions (e.g. north/south).  (Garmin express)

- in app (garmin express or explore? Connect iq 'store'?) license management (add e.g. north america region license for europe devices, list additional topo maps)

- reserve space for private map files (i like the open topo maps a lot because the routing algorithm for e.g. walking / shortest way search can be applied far better than on the bicycle optimized maps that never give you the shortest path)
