Hi my name is ***** ***** I will be happy to assist you.
How old is your device?
Did this suddenly start happening or was it after an update of sorts?
Alright, have you tried performing a Hard Reset?
Does it allow you to perform the above steps?
Alright it seems as if the internal software/hardware is corrupt. Since it does not get recognized by your computer, it may be difficult to fix. However for corrupt software files to may be able to obtain an .RGN file. To obtain an .RGN, you will need to call 0808(###) ###-####and provide them with the serial number of your device. Let them know that your device displays the loader loading message and that the internal software has been corrupted.
Once you have the .RGN file keep a copy for safe storage in case this happens again.
It does make a difference. Garmin cables have a specific regulation that put that device into USB mode. It is possible that the cable being the incorrect cable is not allowing the computer to recognize it.
