I thought the $18 item referred to in the new thread would not fit my
radio, but after a while I decided it should. It should come within a
week.

It finally came (after spending 3 days in Sacramento) and it might not
be the item's fault but it doesn't work. My radio has a CD changer jack
that matched the plug on this adapter, but now I see that nothing in the
radio's manual says anything about a CD changer. JBL or Toyotal E7001,
in an early 2005 Solara. There is an E7002 also in later cars.

Could they have put in a jack in mine that has no purpose?

That seems very unlikely.
