Read through multiple threads on this topic. Have Zumo XT connected. Downloaded maps from Zumo to computer with Garmin express thinking that was the answer. Still the same. Have Highest detail on. Windows 11. Selected maps. See text data points but no town county roads. See my tracks on roads that do not appear. Reinstalled Basecamp.
Just noticed under the mile scale bar is a little yellow message that Map Detail Locked. How do I unlock it? Thought the device begin plugged into computer unlocked the map?
