Again, yes, you can retro fit one, no it will not be cheap. A pretty digital screen that the later model E36 has quirks in is not worth it. I had a link somewhere with a lenghty conversion from earlier E36 HVAC controls to the digital one. If I can find it again, will hook you up. Be prepared for ass pain and alot of time to get it right for just a few pretty red lights you will not use much. Not slamming you....but save the money, used HVAC digital, around 200 bucks....hopefully it works OK, then the trial and error, dash removal.......lots of other things I would rather do with an early model E36 besides that. Just my 2 cents.
