Well, I took the whole thing apart... Removed the plastic, pulled the stingray, opened up the radio, checked the 10amp fuse in the back of the radio, unplugged and cleaned all of the connections both in the front and in the back. I also left the battery unplugged for an hour and a half and tried to reset the unit that way. I still have power at the fuse under the passenger seat, but no lights whatsoever on the control panel. Absolutely nothing happens when I try and power on the unit.
If anyone has any possible suggestions for how to proceed from here, I'm a fairly desparate man and would be open to them! It's great to have this community as a resource. For now I think I'll take a break, as the last several hours have been frustrating to an extreme.
Thanks again for all your help, both past and present.
