I posted this thread because I've seen people searching for it.

Air conditioning...

Can you add A/C to a vehicle that didn't originally come with it? Have you ever done this?

I've heard of dealers putting in A/C as a dealer-installed option (in general, not specifically for Nissans).


Cruise control...

I know the answer to the cruise control question: yes, it can be added. There are aftermarket cruise kits (like this one is for the 2014 Versa Note which may work on the Micra).

Another possibility, if the throttle is drive-by-wire: sometimes it's as simple as buying the OEM buttons/switches for the car -- the wiring is already there and the computer has the programming by default. I've seen people do this DIY with other late model cars (a GM though).
