Just thought of another possibility. Original owner may have had HU changed or made a mod themselves. The 10-pin on the back of the HU may not be fully seated / have bent pins / or been hacked in some way. I think it's worth checking out. Popping the trim and two screws & the HU pops out ...

Sorry my previous suggestions didn't get you anywhere.
