There actually are a bunch of options you can get. So it's not really true that the only choices are transmission and Nav.
But it is true in the sense that there aren't any other of what we might call "major" options -- like anything mechanical or technical.
For example, here's the silly options I got:
-- door visors

-- sunroof visor

-- trunk tray

-- mudguards

-- cassette player

-- all-season mats

-- Lojack
Oh, and I guess you could also say the extended warranty is an option
Actually I'm glad I got all those things.
I didn't get the fog lights, but you could say that's an option too.
