Just happened to mine. Less than three years old. Not happy
Is there a way to install this over Bluetooth? The MicroUSB on my 520 has a broken pin so whilst I can still charge it I cant copy data files! :(
So this is an issue for the 520....I'd like cash back
One of my pins failed on my 520. I looked at my old 500 and it was designed with pins that were protected much better. Crappy engineering on the 520 causes them to break.
I have had this exact same problem with an Edge 520 and now an Edge 520 Plus. The 520 was merely difficult to get to connect to a PC but the 520+ has repeatedly caused problems for chargers, scorch marks on cables and my laptop will actually put up a dialog saying that it has shutdown the USB port due to a dangerous short. When I called support they wanted to charge me $110 to replace the 520+ even though it's still under warranty.
I have never had USB ports fail on anything except these Garmin devices.
The next GPS I buy will not be a Garmin.
