I've got the factory GPS/Stereo/6-CD changer headunit that suddenly stopped putting anything through any of the speakers. Nothing, not even a hum, buzz, or pop when adjusting the volume up or down- they are completely dead. Sound settings are fine. Initially the headunit touchscreen & hard buttons (including steering controls) will respond normally- the GPS seems to function as it should, mode selection, volume up and down appear to work fine, just with no audio with any of the modes.
I say initially, because I can force the headunit to lockup and not respond to either the touchscreen or key presses if I work the volume too fast or too many key combinations. The screen will typically flash, then be unresponsive. Otherwise, if I handle with care, the headunit will function like it should- just without audio to all of the speakers.
Is there a hidden amp fuse or anything else I can check before trying to find another headunit? The passenger-side block does not appear to hold any headunit fuses.
