My 2007 RX350 has no sound coming out the speakers when I turn on radio, or CD. The control knobs and panels seem to funcation just fine, but I can not hear any sound. The audio from Nav system does work, though. This happened to me a couple times before. But those times after I stopped and parked it for a while, the sound came back. This time it seems I can not get the sound back even if I stop and park the car for a while. Anyone has similar experience? Thanks a lot.
