is it easy to fit an automatic climate control system in our cars? anyone has done this?

 

I would think you could use the the JDM 96' and earlier Prelude componets that are fairly easily available, but than you would have to probably put them in the readio compartment and move the radio elsewhere. So not that probable.

The Acura TL (and others probably) with Nav uses the in dash display to control the climate system, with considerable expense you could go that route and get Navigation as well. THere would be considerable R&D time getting the system installed in the dash as well as making the manual climate system we have work with the automatic of the Acura's, but as with all car issues it is possible with enough time and money

This might be one reason to use the Honda / Acura system rather than an Alpine system...

 

Remember they have those temp sensors too
