Hi there Robbie. My name is*****'m sorry that you're having this trouble. I'll do my best to help.
USB communication issues can prevent Garmin Windows applications from communicating with Garmin devices.
If a Garmin mass storage or MTP device is not detected by a Garmin Windows application, check to make sure that that the device recognizes the USB connection. Most devices will display an icon on the screen indicating that the device is communicating with the computer.
When a device is properly connected to a Windows computer, it will be displayed as a removable disk or portable device. To check whether Windows recognizes the connection:
*For Windows 8, press the Windows key + X and choose File Explorer
Mass storage and MTP devices are both listed under Devices and drives in Windows 10. In older version of Windows, mass storage devices will be listed under Devices with Removable Storage while MTP devices can be found under Portable Devices.
If the Garmin device does not display the connection screen or is not recognized by Windows, try the following steps:
If the Garmin device is recognized by the computer but the Garmin application will not detect the device:
The Garmin device should now be communicating properly with the Garmin application.
