So just a random question. I have a 2012 sonata gls and I love it. But the head unit just seams “dated”. My girlfriend’s cousin has a 2011 limited and has the touch screen and navigation and looks WAY better and has far more options like HD radio and bluetooth audio support for changing songs with steering wheel controls. I understand that the faceplates are different between the models and I don’t have any gps parts for it to work, but is it possible to swap out my basic stock head unit to the stock touch screen head unit? Will it be as sinple as plug and play and replacing the faceplate? I have basic HVAC controls but wish to keep them. Would I need to swap HVAC units too? Really curious but there is no info online that I can find just by googling it. I don’t want some crappy aftermarket touchscreen unit with glitchy software and that doesn’t support the steering wheel controls that I have become So accustomed to thanks in advance!
