Monday 11/3/2014. Weather temp 43F. Time around 6:40am. Driving on highway. Radio has been on since the car started 30mins ago. Around 6:40am, there as some kind of static or sound like from firework sparking stick that was coming from the speakers for serveral minutes. I thought may be the radio channel need to change. But before I changed it, the radio screen was turned off and blank, and the radio channel still was playing. And then the radio screen was back to normal being on again, the radio channel was still playing, but the sparking noises from the speakers were gone. This has happened one time. Bizzare? And yes yes, I only have the basic model with radio equipment only. :)
