I too am having issues with the mylink infotainment system. Mine does the no volume or turn signal noise and no xm stations at all. no indication that xm/sirius was ever in the radio at all. Have had this issue last year 4 times. This issue occurred when temperatures are below 30 degrees. Possible issue is when it gets really cold some resistance in the wires play havoc the the audio system. still having issues with and has happened 4 times in the last 2 days. Twice a day this happens. Great truck for a year but this does not happen during the warm months just the cold months. I do not want to deal with this the next six months in the cold Minnesota winter. Is there a fix besides pulling the radio fuse? Done that as well and it does fix it but it still happens. Replaced the fuse and it still happens. Now no xm radio just fm and am. Not happy with this. I will have to get out my sirius radio portable and make it work till this gets resolved. Anybody have suggestions besides going to the dealer which i will due to a steering recall.
