I don't think that I have the Lexus Link System. Is your best guess that my stereo mute is causing this problem? I will never ever care to use a phone in this car. Given that, can I go to the stereo amp in the trunk and disconnect the mute wire from the harness? Will that disable phone muting?

You might be able to get the amp repaired at www.autoecu.com

www.autoecu.com might be able to rebuild your amp if you determine the amp to be your problem.

I had good luck having my factory amp rebuilt at www.autoecu.com

I tried that just now and it did not work.

I recently experienced the no volume issue on the ML audio system. The stealer diagnosed a bad amplifier and a mere $750 part + labor. I declined. Sent the amp to a place I found that will repair it. (www.autoecu.com $249.00) Re-installed the amp and still have the issue of no volume. Nothing. Tuner appears to lock onto a station fine just no audio at all. With the audio system turned on and max volume I can hear the radio for a fraction of a second when I first turn the ignition switch on. (Powering the audio system on and off will not recreate this.)Read some more posts and I am leaning toward the idea of the phone mute perhaps being stuck in the mute mode or some such malfunction. There is no phone in this car. Read that there is an orange plug under the rear seat that you can unplug to disable the phone and perhaps fix the issue. Trouble is, how on earth do you remove the rear seat ? I can barely get my fingers under the front edge. It appears that there are some brackets bolted to the floor but I cannot create enough room to get a wrench to them. Any ideas? My car is a 2001 LS 430 Ultra Luxury with the Mark Levinson Audio System

Guru, Is there a chance I could get you to contact me. I am having an issue with my stereo. Looking at other posts, I think you might be of great value. dlybarger@yahoo.com PS: I tried to send a message and an email but the forum would not allow me to.
