Long story short, I just purchased a 2008 Santa Fe Limited with the Factory Infinity speaker system and the RSE unit. I'm not a huge fan of the factory head unit, and would like to replace it. Is there a way to do this without causing the RSE to become inoperable? I don't really care if the RSE plays through the car speakers, as I can run it through headphones.

Any information would be great.
