I found the update on the Kia website It is for a 2015 optima the closest to my 2012 Optima. Can I put that update on my 2012 optima? there is no update for a 2012 optima for Navigation on the website. I have a 4. something and this is a 5. something. I think is the right update just want to be sure. I don't want to screw up my navigation with the wrong update. Anyone done this are know?
