I have always updated my maps through the connection to my Mac device, but since I have lately updated my device (nuvi 2547LMT HWID:1582, version with lifetime Europe map updates) to the 5.50 version my device isn't seen by any of my Pcs or Macs. I have tried Mac Catalina, older versions of Mac, Win 10, 8, 7 and even XP and other modded versions of Windows (JG). Every time, the Garmin app failed to recognize that my GPS device is connected to the PC/Mac so I can not update my maps, the system on my GPS or revert to a previous version. I have tried formatting the disk of my Garmin device, restoring it to default factory settings. Even since I have installed new cracked maps through a SD card and everything works like it should. Is it possible to install my system again only through using a SD card, without using a Mac/PC, or perhaps some of you have any other solutions to my problem? Thanks for the help in advance.
