My automotive power outlet does not work so I can only charge my one year old ,Zumo 220 with the USB cable. This has always worked fine.
I'm going on a trip so I topped of my battery today even though I had two bars left. When I plugged the unit in (power off) into the usb cable (already plugged into pc) the gps kept cycling up and down. I disconnected and reconnected each end of the usb cable with no change. So I moved the gps and cable to another computer with the same results.
I move it back to the original PC and all was well. Its charging now so I don't want to disconnect it for any testing. I would like to get a few hints incase it continues this rebooting while attempting to charge behavior.
idea's?
