Looking at your profile, I think you are in the wrong section of the KIA forums.Here in Canada the SX comes with Standard Heated Steering Wheel( With our Climate a Great Feature) & Single Zone Electronic Automatic Climate Control( which works great!).Only option for our SX is Navigation.We also can get Beige or Brown & black Two Tone Leather. We pay about $2000 more than in U.S.A. I have a 2013 Signal Red SX Sedan With Beige Seats,Dashboard, Door Panels & Black Carpets. Kind of gives it a Mini Ferrari look. So far love it & averaging 33MPG in mostly city driving.
Funny, I never knew my SX had a memory seat. Not that I care since I am the only who drives it (okay, the gf will drive at times, but she only moves it forward).I don't have an SX but the sales brochure and KIA website shows a memory seat in the SX Premium pkg.
A lot of forum members are like salesmen....opinions not facts.
