I installed "Garmin City Navigator Europe NTU 2022.10", I try to upload map to nüvi140T but MapInstall gives me: "The data was not successfully sent".
I tried in MTP and in Mass Storage mode also, same error message.
I deleted OS manually from its internal memory and reinstalled it with WebUpdater, same error message.
I tried to install map on a memory card by copying first from internal memory the GarminDevice.xml file on memory card's Garmin folder, same error message.
Ps. I unlocked map with "UnLock MapSource" if its counting anything.
Before with any devices and maps I didn't had this error.
