Each car has a developer mode can be accessed by special code or by secret pattern touch on the screen, this mode can help to change and activate some exrta setting in the car which is disabled by the manufacturer.
I was searching the web from long time but nothing mentioned about Cadenza 2014 navigation, you can find 15 & 16 model but 14 is different version.
Even updating the system through Kia website is not available for 2014 model only.
It is really strange that Kia has putted two different Navigation on the same model.
Normally the manufacturers upgrade the existing system yearly and change it when redesign the car but Kia did not!!
It is not the matter of the Navigation only, do you know that the keyless remote control in 2014 is different from 15 & 16 model?!! It is the same from outside but inside: the Board, the battery holder and the frequency range is not the same!! Quite strange, is it?
