Hi,
I just bought my Garmin 2 weeks ago and really enjoyed it. However, just this morning halfway through my training, the buttons of 520 are suddenly no longer responding. I try to make master reset by holding on to the power button, but nothing works; all the other buttons still remain no response at all, even the power button to adjust the brightness. However, it still able to detect sensors and GPS and connect to the computer by switching to mass storage.
Someone please assist me on this.
Thank you.
