I've had this vehicle since 2010, but over the past seven months, there's been an intermittent problem in that when I hook my iPod Nano to the USB port, it doesn't recognize it I would say 75% of the time. I've noticed that this usually happens in the morning or when I start up the vehicle. It will say "Aux Jack Out." After 5-10 minutes, it will finally say "Device Not Found." But if I hit Aux again right after I get that message, it will be recognized and it will play no problems. I changed the fuse and it still persists. I've tried different cables and still have the issue.
