I have the ML sound system in my 2001 GS430, a few days ago I started the car and the radio blasted for a split second and then the rear speakers cut out. No problem I know this is a default feature to safe guard against any serious damage, however I had the radio turned down very low before I shut the car off
Now here's the strange thing I shut the car off and re-started the engine to reset everything but the radio adjustments (Base, Treble Mid range) were all screwed up
I attempted to reset them but the touch screen would not bring up the Base, treble or range for anything. Thr green light that would normally move up and down and you press the controll was non-exsistant
I waited and played with the Base and a few minutes later I was back in business, then a few minutes after that the Treble came back and eventually the Mid range-WTF?
I making an appointment with the dealer to have this checked and another small fix but I was wondering if this has ever happened to anyone else?

Yep, I have had similar odd things happen with my 2001 GS 430 ML system. Things like the CD AND Radio playing over the speakers at the same time - and no matter what I would do, the CD would continue to play (AM,FM, Tape).
Also, I have had similar things happen to my NAV where the touch screen stopped working all together.
Interestingly enough, when I turned the car off and came back to it the next day, everything was back to normal after the car went through its power up diagnostics (which is why it takes so long to crank the 430 as I understand it).
Only other problem is that I lost my amp (it overheated and failed). This may result in the same problem you are having with volume going up and down or not maintaining where it was last, that is somewhat the same as what happened to me. If you are under warranty I would have them look at the amp as well. Obvisouly this is a disappointment given the premium we paid for the ML set up...
Good luck - hope you get it figured out.

I believe that there is a TSB on this one. Lexus has replaced some ML amps for this reason, apparently w/o recurrence of the problem. Take it to the dealer; they shouldn't act surprised.............

Hey bro- sorry to dig up your old thread here...but I could REALLY use your advice on this. I am having the EXACT same problem. (the MID and TREBLE are missing usually, or at least just the MID line and the green light)
NO SOUND at all. It was coming on/off and making a popping sound, etc.
It would also just come on at FULL VOLUME then go off immediately after.
What did they end up doing to get your '01 GS430's ML speakers working again?
THANK YOU SO MUCH for any input on this
