Unit will turn on only after holding down the

Charging plug is broken off of the printed circuit board. Battery is extremely low on juice, so it won't fully turn on. Once I get home I plan on splicing the charger into the battery wiring directly to see if that will work. This is the second magellan I've had...the other one did the same thing. I'm guessing that it's the same problem. Haven't dropped either one of them...other than they like to fall off of the windshield (suction cup). Seems like they need to come up with a new design (for the circuit board).
