This morning it worked fine, but this afternoon my MM3 screen is blank.

The light on the right of the screen blinks red, red, green, red, red.

Then a pause starts over again.

I tried to unplug it momentarily, possibly to reset, but that had no effect.

It blinks all of the time. Even with the ignition turned off.

Any thoughts or advice is greatly appreciated.

P.S. It is only about three months old.

Thanks!!!
