I got it working again by reburning V22.1 on a Mitsui Gold CD-R. Used clone cd and burned at 1x. I just popped the CD-R in, waited like 2 mins. Pushed the right turning knob on the Navi, as if I were pretending the accept screen is there, and all of a sudden it came back to life and started loading the update. All is well now. Let me know if you have any questions.
