Hey, i own a 2004 lexus gx 470 and i am having some audio issues. The stereo system is the standard Mark Levinson speaker system. When i turn on my car, i can cycle through the different radio stations and cds, but there is no receiving audio coming from the speakers

Run the audio system diagnostics.

Hold the Audio and Climate buttons down and turn the parking lights on/off 3 times using the stalk.

Can you post a photo of the screen showing the diagnostics or just type in what you see?

More than likely the amp has gone bad, but the diagnostics will be a big clue.

Thank.

Going through the same issue. Ran a diagnostic and got the message check H/U. Going to just replace the head unit. Let me know if you get yours sorted.

My audio and a/c isnt responding. I held down the audio and climate controls switched on the headlights 3x until the check system appeared. It displayed the NCON for audio and DSP-AMP. How do I correct this issue? Also notice that my outside temperature doesn't display either.
Thank you for any reasonable answers.

This what it shows. Thank you for any suggestions.

Check the fuses.
Also, this forum is for the first gen GX-470. You'll get better help in the forum for your specific model.
