A strange problem started today in my 2005 GX470 with standard audio (no nav, no ML). There is no volume control, no sound from speakers. All functions seem to work just fine from tuning, changing source, etc. There is no sound and when I turn the volume knob or push the volume buttons on the steering wheel, there is no response, no change in the display (normally shows the volume setting momentarily). I checked the ACC fuse and both Radio fuses and they are all good. The only modification I have done was add a GROM bluetooth unit a few years ago. It's been in the 70's here in Boise, no water crossings, no rain leaking into the car and it worked this morning.
Does anyone have an idea what might be going on?
I may need to just replace the head unit with OEM but I'm unsure if there is an amplifier outside of the HU that could be the problem and would continue to be the problem after plugging in another HU. I'd hate to have to run new speaker wires throughout.
