do you have a aftermarket installed? like a phone kit or something.....
I just experienced the same thing! HELP!
My lexus rx300 plays fine. I was listening to my ipod using a tape deck adapter. When I noticed that I couldn't adjust the volume on the lexus dashboard... only via my ipod. I could adjust both from the ipod and the lexus volume control before.
Then 5 mins later, static, and all sound was gone. I couldn't hear anything via the lexus radio, tape deck, or cd changer even if volume was maxed. But if i max the volume and play my ipod via the tape deck and max the ipod's volume, i could hear soft music coming from the ipod.
Now i can't even mute the volume on the lexus nor adjust the bass, treble, etc.
The dealer says I need to change the entire radio and that the radio is the culprit. And they are charging $650. WTF? for a radio? $475 + tax and $150 for labor.
