Try this: Hold the power buuton down, you will see on the lower screen the word "Pre Booting - ". Keep holding the power button for about 60 second, then you will see on the lower screen "Booting".
This time, release power button; system will reboot and loading map... again.
I got the same problem, after research on the web. Nick 99990_0 had post this solution on (his Nuvi 660) but it work for my Nuvi 350 too. Good luck.

You have to power the unit via the mount by either using the cigar charger in the car or snap off the mount from the ball and socket and power it via the mains adapter.

The problem with repairing it yourself is that this is a surface mount connector. The solder pads are so small, it would be very difficult to solder with a standard soldering iron. Most likely you would apply too much solder and short out the connector. You really need to use a surface mount soldering/desoldering device and that can be fairly expensive. I have done this before but I have access to the right equipment.
Also, there is a possiblility that the printed circuit board tracks have been pulled up off the main board. If that has happened, there's a lot more work involved in fixing that. You might have to put in a different type of power jack and run wires from it to the main board.
If you're going to try to salvage the USB connector, I would remove it completely and install a new one. Over time, these connectors wear out, so you're better off removing the old one and putting a new one in. Again, this all depends upon whether the tracks on the board have been damaged or not.
Please let me know if I can be of further assistance to you.
Good Luck,

You also have to know how to take apart the Nuvi.

If the Nuvi won't charge when connected to charge but charges on USB, then the charger port is faulty.
If the Nuvin does not charge at all , then the battery must be replaced.
