Ever since I've had my Explore 2, it has failed to charge intermittently.
When a charger is connected the unit powers on but will not charge unless it is turned off. It seems to use so much battery searching for gps, phone, accessories etc that that all teh charger can do is maintain the battery charge. So I have to turn it off, the problem is a few minutes later it turns on again and we're back to it searching and not charging. I literally can leave it for days connected to a charger and get no charge.
