the '12 ram seems to do it once a week or so. The Charger did it the other day, not sure if it was doing some kind of OTA update or not.
i'm guessing that its also limited to the Radio's with Nav since its caused by sirius travel link. does 4c designate the nav radio? lol
4c is the generation of radio. 4c radios had the android auto/apple thing. Suppose to be upgraded hardware too. Any 17-18 radio nav or not that has travel link could be affected. Travel link is free for the first 5 yrs. Thats all part of the XM radio
so yea, only the navigation radios because the 5 year travel link subscription is part of the navigation upgrade
