I have a 2015 HSE LUX and the xm will freeze up and only lines will be where the stations should be. So you are stuck listening to what you had on. also my whole nav system went black for a day and then came back on. All the scrolling song titles are always for the song that just went off, not the one plying. They updated the software at the dealership but still does this. Any one else having a problem?
