No, I was not the one who posted part numbers.  I know there are
kits costing about that much to add an air conditioner to a car that
did not come with one.  The last couple years A/C has become a popular
option in Germany and the great majority of used cars don't have it,
at least up north.

Glancing at the ETM schematics, I think there might be a fair amount
of work converting an analog dial system (IHKR) to a digital button
system (IHKA).  Even mundane signals common to both get wired
differently.  But perhaps like retrofitting an OBC, the job is easier
than it might first appear. :)
