I have a garmin 520 which froze during a recent ride. I switched off and back on thinking it would solve it. Unfortunately it didnt. When i switch it all i get is a message saying loading profiles. it is trying to load everything and start but unfortunately it doesn't. I looked online for troubleshooting and find some advice to reset factory settings by holding down the on/off button at the sam time as the lap counter button. That didnt work either. Someone else also suggested trying to connect it up to Garmin Express or the Garmin web updater and that failed as well because the device was not detected!!
Any ideas on what else i can do?
