cold weather radio issues
 

On very cold mornings I get no sound from the radio. The unit is on. Same thing from the factory DVD. Headphones have sound but nothing from the speakers. After about ten to twenty minutes of driving after the car is warmed up all of a sudden the sound starts flowing. Only on cold mornings. It is a 2005 Pathfinder 6CD with the Bose speakers. Is anyone else having similar problems.
thanks
