I posted about this a while ago and since many SW upgrades have not fixed it I thought I would try again.. When I first get in the car and it has been left in radio mode(AM/FM Only) the radio sound occasionally cuts from static to sound repeatedly for about 5 seconds then resumes sound. I have asked service a couple time and they have blamed the HD feature (not true), and SW updates (also not true). I got a 2014 loaner at last service and it did the same thing!! Its not a consistent thing and appears randomly, only on entering car, and Only with AM/FM. Anyone else with this issue and (maybe) a fix?
