Hello,
I' ve got always a white screen on my Garmin 1050 just after the dowload of a course map from Komoot premium application installed on my mobile.
After switch off/on the Garmin handset, it is ok. Mean I can access to all Garmin functionality and then, to the course map I have loaded from the Komoot application installed in my Garmin Edge 1050
Thanks in advance for your support
