Same issue.Not enough space to install the maps after recent update 27.13! Standard 540 Garmin non-solar. I ride on PL-DE border and have problem. Repair this quickly.
There is currently a bug where the new Topo map installation is not fully removing all the associated files from the Cycling maps when doing the upgrade. Garmin are working on a fix.
strange. I didn't have the problems described above. Maps before update was from 2022 (both central and west eu) and trailforks. Adres update 3GB free spacer. GE 540 non solar.
