Pioneer used to make a full din control head with a seperate "brain" that
would do this. Can't recall the model number at present.

Pioneer's 9400 and 9600 head units do this. Sends out test tones,
records level, shows the analyzer. Then you can manually adjust the
bands with included 13 band equalizer.

I thought some of the newer Bose stock systems did this as well?

Does anyone make an equalizer that will automatically adjust its
settings when connected to a real-time analyzer? I was looking at
the
AudioControl SA-3055 analyzer, and it has the capability to convert
your car's frequency response curve to an IASCA score. If you could
design an analyzer that would provide feedback to an equalizer, you
could program the final response curve you want, then have the RTA
analyze your current response curve and automatically send control
signals to the EQ to change its settings until your in-car response
matches the curve you specified, or at least as closely as possible
within the limitations of the EQ. Using this method, EQ adjustments
would take a matter of seconds to complete, and would be extremely
nice if you had a particular response curve you wanted to match,
such
as the IASCA grading criteria.

Adjust for a sound source or for the sound system?

Blaupunkt and probably some other brands have self-adjusting EQs.
They
play tones and listen for the response on the mic. The HU I have now
will even record multiple entries to represent the proper EQ setting
for
different seats in the car. Mic not included, of course.
