UPDATE.

It works PERFECTLY through a ground-loop isolator, this one from Radio Shack in
particular:

http://www.radioshack.com/product/index.jsp?productId=2062214

Part No. 270-054, US$16.99.

This suggests to me that there's probably a DC offset originating somewhere
(Car->Neo or Neo->Car) that the receiving device doesn't react well to.  I don't
have a 'scope so I can't really verify which direction it comes from.

But in either case, it appears the audio output stage of the Neo is non-standard
to some extent, and I'm leaving this bug open for now.
