different AC knobs for NAV vs. non-NAV
 

guys, after 3 years, i just finally realized that 370Z with Navigation has different Air Condition knobs than non-Navigation equipped models.

basically, non-Navigation model has "Bigger" 3 knobs.
Do you guys mind explaining why this is?

The only thing I can think of is so that you can't change your head unit...?

I've always known they were different... But not a damn clue as to WHY... Never really thought about it until now... I think the smaller knobs look cleaner and the Nav setup looks cleaner, but I don't like the A/C on/off light...

Yeah, it just looks "nicer" every step up you go:
