My Garmin GPSMap 62s has worked extremely well for me for the last 6ish years. Now, however, when I switch it on it thinks I'm in the English channel, then finds me correctly for a nano second or two, then puts me back in the channel - very frustrating.
I've switched it off and on again (several times), checked the sd card is secured, all looks well, new batteries etc but the problem is persisting. Is this the end? Does this type of garmin only last 6 years? Is there anything else I could be doing?
