Digital climate control was a factory option on the S13's, you'll need the different wiring loom like the other fella said and to be honest most of us could find other uses for the $300-400 bucks its going to end up costing to patch it all in there.
It does look nice, a friend of mine has it in his Q's but my K's dosent have it as standard or anything. Bit of a wank really, at least with the old-school analogue Ive got half a chance of fixing it if it breaks and theyre cheap. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
Do you guys get the HUD in the S13's over there in your 240's?
