Back Butters

Started up as in instructions and the following happened:

USB Device came up with : Zumo ID 3475****** etc.

Hit the OK button.

Software Initialling Version 5.00

No update available for your product.

No update successful on my pc screen or on the Zumo screen or software loading. Did try this again in case I had left it to late releasing the button and one time the Zumo screen came up with a grey background and a black icon labelled "spot" with black vertical and horizontal lines guessing that was for setting up for finger touch calibration? So no success this time around. My son is pretty good with computers but unfortunately in the RAF and not home until Christmas. Kept the battery out all the time as this would start it up flashing between screens. Had finger on top left + button at the same time the bottom RHS power button and a finger on the screen in the RHS pressing all the time then releasing the power and + buttons. Within 2-3 seconds the Zumo ID 10 characters appeared.
