Sorry, FWIW, for the benefit of onlookers who dont know this unit, it
has TWO usb ports: One for power in the back and a separate data-only
port to plug it into the computer at the side. It buzzes until the
side usb port is connected to a computer, - it gives a splash-screen
and then as soon as the connection is recognised, the buzzing stops.

I'm confused.

According to the following guide, one of the three options for
charging the battery is to "connect the AC adapter to a wall outlet
and the mini-USB connector on the side of the nuvi".

A second way is to "connect the USB cable to the nuvi and your
computer".

The guide does not mention two USB ports.
