I have had one problem after another with my device. Pairing it was the first problem and Garmin replaced it for me with a reconditioned one. I was all set to use it on a club ride today. It missed telling me about one quite important turn but then it just stopped navigating completely. It started again about an hour and a half later and 10 miles away (we had stopped for coffee). I was following a group so it wasn't a problem but I have no faith that the device will navigate me correctly if I am on my own or leading a group. I am so frustrated and can't think what can be the problem with it. It has recorded the ride accurately so it wasn't a signal problem. Any advice.
