I have a new Limited with the NAV package - among the 90 day XM promos is Nav Traffic. On start up, and after touching the XM options icon (lower left on touch screen), three of the four: Stocks, Sports, and Weather will all load in about a minute or so but the Traffic does not. I had XM re-flash my activation but it still isn't there like the other three - either I'm doing something wrong, OR the unit is malfunctioning OR the car needs to be in an area that has traffic reporting. Anyone else having luck or am I doing something wrong? Thanks in advance - not much activity on the audio electronics board so I thought I'd try here because it is specific to the '11 Sonata.
