Thread: Need to REPAIR a 3790T

The best and the fastest way to charge nuvi's battery is the wall to USB charger. For 3790 genuine's charger specs are 5V - 1A so any charger with these specs should do the job but as dasil mention you must let the battery charge for a while. If your new battery is drained then after a couple of hours of charging try to start your device by keeping the ON button for about 20 seconds to see if it comes to life.

Ooops Neil was faster than me ...
Mod. Note: LOL. First time for everything Mate. BTW, Dasil would have told him too if we hadn't.
