Query: Adapter broke with normal usage

I would have put this review on the GARMIN 770, but it is no longer available.The charger is very poorly made. My Nuvi 700 series gps was very expensive and should have had a good quality adapter. It did not. After several uses, the garmin stopped taking a charge. I found that if I wiggled the connector, the charge would begin. So, something in the connector part of the charger is crap and of course, the GPS is now useless because the battery is dead.
