My magellen 3100 battery will not charge

its probably not charging...very common problem with this and many others.

make sure green light is on the car charger and let it plugged in for awhile, then hold the power button (upto ten seconds) until it starts..if that fails

the following magellan 2000,2200t,2500,3000,3100,3140,4000,4040,4050 and the 6000 are known to have faulty dc connectors...if your magellan gps is not charging or will not power up, its most likely the dc power port...

you can get it repaired, here
or buy the port here

if you need further help, just let me know.
