The brochure is wrong about that deletion. Early build NAV units don't have HD Radio, but the USA/AUX input is definitely there. I had the same concern before I purchased my Limited w/NAVThe 2011 Sonata brochure states that the navigation option deletes the USB/aux input for mps/ipod players. Can someone who has an 11 Sonata tell me if this is really true? Also is there a cost for the traffic service on the 11 navigation option?
