i have a 2012 Sorento SX. It came with the nav and upgraded stereo system. It also came with a complimentary subscription to Sirius/XM radio as well as traffic. I never extended subscription to either the radio or the traffic after they expired. Recently i've noticed that the traffic icon is missing (not greyed out) when i use the nav. Its been over a year since our subscription ran out so my question is, where did the icon go?
