I have a 2012 Genesis Sedan with the Technology Package. It still has its original maps that probably date to early 2012, or possibly 2011. I have it at the dealer for a service, and am considering the map software update as long as they have it in the shop. Are there any user general system interface or feature benefits from jumping from 2011 or early 2012 maps to the latest V11 2017 maps? Or, are the only updates to the map data themselves?
