Fixed a non-connecting 660

Post by danham »

I was attempting to update my maps today and the zumo was acting very strangely. Plugged in to my iMac's USB port, it would boot up, say Loading Maps, ask for the PIN lock code, then reboot. It would not mount, ie show up on my computer. The only clue was that it would speak, "Please drive to highlighted route."

OK, so i went to the home screen and tapped the X to kill the route that apparently was loaded and in progress. Still no joy.

It required disconnecting the zumo, booting it, once again canceling the route that had stubbornly stayed active, and then shutting down and then connecting to the USB port. This time, it mounted on my desktop and I installed the new map.

Hope this helps somebody -- having a route active appears to prevent the zumo from being recognized by the computer, and you cannot cancel the route successfully while it is connected.
