Radio/Nav Display works, no sound - which fuse?
I have a 2005 RX330. I just turned the radio on (with car running) and no sound. The radio's display lights up, showing different station #s as I select them. The clock is working and set right, and the nav system is also working and displaying properly.
However, the radio produces no sound no matter which station or mode I select. Curiously, the nav system "beep tones" are also absent - like when you switch from the NAV display to the CLIMATE button, usually it make an audible beep, but now nothing. Also, when I press in the radio's right hand **** and get into the audio settings (Bass, Treble etc.) I can neither increase or decrease their amounts turning the ****.
Since most of the system is working, I suspected a blown fuse, but I have removed/replaced all the fuses that relate to "radio" or "amp" in the manual, and still no sound. I can keep pulling & checking every fuse, even ones not listed as connected to radio, but before I do that, I thought I'd ask here. Any suggestions?

Some owners have detected a poor connection & some a defective amp, also some owners with ultra Hi-Fi quality ears refer to the original amp as a sub mediocre quality amp & replace it even though it functions.
