I have resolved this issue.
~~~~~~~~~~~~~~~~~~~~~~`
Hi,
I just received my new Forerunner 970 and attempted to install an OpenStreetMap (OSM) topo map by copying the map image files I had previously used on my Fenix 7X. After transferring the files into the “GARMIN” folder on the FR970, the OSM topo map failed to load on the device.
Has anyone else encountered this issue? Has Garmin disabled support for third-party maps on the Forerunner 970?
Allen.
