I returned the JVC to the supplier (it's only 2 weeks old). They say
they tested it and found no problem - had it running "all afternoon" -
and returned it to me.

Could anyone offer any advice/suggestions?

Try connecting both power feeds from the head unit (red and yellow) to
the red cable temporarily. If this results in the JVC working with the
ignition on, you've blown the car fuse in the permanent live feed.
