My Factory stereo on my 2013 Kia Optima SXL with Nav/UVO shows the heater controls on the screen and the vent output such as feet, defrost, etc. will this allow that information to still be shown on the screen of my aftermarket stereo?
Robert G on Nov 9, 2014
Best Answer: Hello Robert,

No, you will lose those features. Unfortunately, there isn't a harness that will retain those on board display features.

I have a 2011 Hyundai Sonata 2.0t SE (auto climate control & amplified sound system by Dimension). Will the HYKIA-01 allow me to integrate the factory amp when I install an aftermarket head unit?
