This option only came with F-sport or Luxury models, but I would like to install it on my base model.

Has anyone successfully done this to their UX? If so, please teach this young grasshopper your ways.

 

I don't think it's practically possible. Even if it was, it would be absurdly expensive for the mirrors w/ motors and glass for your options (BSM etc). You'd have to have the control panel, the wiring (which likely doesn't exist on your car). the options on Lexus cars are pretty much best purchased up front.

on german cars like BMW it's easier cause the wiring already exists for most options. then you hook up a laptop and code it. (once you have the hardware)

from what i gather the wiring installed on Lexuses are specific to the options it came with.

 

I was only able to do this
