One thing I DO know, Northern, is that a weak or dead battery will not destroy your tunes, either what's loaded in the PCM or in the programmable memory of the Gryphon.

Consider: you can take the Gryphon out of the vehicle for extended periods (which is equivalent to having no battery) and, you can take the battery out of the truck with the same results (although the PCM has to relearn its idle strategy and maybe a couple of other things I think after an extended period with no "keep alive" power).

The technology in both the Gryphon and the PCM is similar (maybe the same) as what you see in USB "thumb drives". Now, if you were to zap any of these with high voltage, all bets are off.
