I think I've seen this info posted before in response to other questions about lack of power, charging etc., but someone might find it useful ...
Roynie has been having non-stop problems with a second-hand Zumo 550 unit that he was given, with both a car and a bike mount, by an American friend. It would work in the car, but would only charge intermittently on the bike. Often he would just have to charge the unit from the mains overnight and hope that he had enough juice to keep it going for as long as it was needed the following day.
He posted a question on the Triumph forum and got a response telling him to take the battery out for a few minutes and then put the unit on charge overnight (to ensure that the inaccessible internal battery also charges).
If taking the battery out doesn't remedy the problem, call Garmin on 0808 2380000 (UK users).
Now here's the good part ... there is a known issue with the 550 mount, in that it is not very waterproof and is prone to corrosion. Assuming that the unit is out of guarantee, Garmin would normally charge £110 to replace it with a refurbished Zumo 550. However, because they are currently out of 550's, they are sending out brand new Zumo 660 units (with new bike and car mounts) for the same price!
If you've been having problems for a while, now would seem a good moment to call Garmin
