I've had my Nox for a little over a year. I live in New Jersey and the weather has just started to get cold over the past few weeks. I've noticed that on real cold mornings, when I first turn on my car, I get a static noise for 2-3 seconds coming through my left front speakers. Has anyone had this issue or know what it might be? It doesn't happen everytime, so I don't want to bring it to the dealer just yet. Thanks.
