Mark Levinson Amp Failure
I have a 2007 LS 460L and the Mark Levinson amp just failed, so the radio, hd player and bluetooth don't work. I've stopped the very annoying clicking sound that is diagnostic of the amp failure by removing the 30 amp fuse under the passenger side dashboard. I've had a lot of cars, of all price ranges, and this is the first time an amp has failed. Based on the numerous posts I've seen here and other sites, and my personal experience, I believe this is a design or manufacturing defect, as an amp shouldn't fail like this, particularly one that we've paid thousands of dollars for on a premium sound system. I'm talking to Lexus Customer Service and hope that they will recognize this as a design or manufacturing defect and replace the part.

Only under the Platinum Warranty this is covered - Stereo Component Amplifier.
As I mentioned a year ago in post #7, Lexus may need to warrant these for a longer period or face a possible class action suit.

Retrofit ML / NAV amp to non NAV equipped car
I have a '07 LS460 that did not come with NAV/ML (std radio). Those units are available through auto salvage .com sites. Is it possible to drop one of those units in, and enjoy those features without a lot of special wiring etc? If so, what is the unit number specific to that year/model?
Thanks!
Thanks!

I haven't physically looked at the amp, but I guarantee that you cannot just drop any single amp in and have that run your entire car's worth of speakers. Plus, you'd be spending a LOT more than $325 for multiple amps, custom installation, etc.....

Lexus Does the Right Thing.....
I called Lexus Customer Satisfaction and told them of the amp failure problem, and my belief that it was an engineering design flaw based on what I had seen on the web. They were very courteous and got back to me in a few days and said they would cover parts and labor for replacing the amp, even though my 2007 LS460L was out of warranty.

DAMN !!!! I was driving home today and I starting noticing a little rattle/distorion from the speakers at high volume. I have a feeling my amp is about to go. I read one other post about the same kind of distortion from the speakers but I wanted to see if anyone else knows this symptom. I also noticed that when I pulled into the cooler garage area it got a little better. I am assuming the amp is overheating and about to shut down. I want to take it in before it blows totally and I have no music. This is getting a bit common now.

I think its the amp because its doesnt do it all of the time and it gets worse when the car is hot from sitting in the AZ heat. I even hear the buzzing noise when the volume is low

Mark Lev Nav system-sound cuts out
I have a 2004 with the ML and Nav system. The sound has started cutting out, all channels. I moved the fader control to the front speakers and the sound is fine, left and right. If I add the read speakers, the sound starts cutting out. If you turn the volume control down is works for all channels.
If the volume is turned up past 1/4, the sound cuts out. I presume this is a power amp issue but since it works on the front channels, I am not sure. The power supply for the power amp is working I guess since there is full front L/R sound. I also guess the subwoofer is driven off of the read channels. I am also getting DVD ERROR when I insert the magazine. Not sure if these are related as the system has a communication bus that talks to all of the components.
Any guesses??
