I recently decided to update my device to keep it valid. Prep phase completed with no problem, Map update however fails at 64.1% time and time again, I was using a 32Gb in device, replaced with another card, same result. Useful point was that I found a button that said download Map to PC, this completed OK.
However Map Update fails time and time again at 64.1%.
At the minute I have my iPhone strapped to my Garmin and I use that, I find it a much better device but would like my Garmin in working condition.
I have found lots of closed posts but no solution.
