LS007

Installing a hand free phone kit in my LS430, center console (pictures to come) I was very happy to discover the radio mute wire worked just fine on the Mark Levinson audio system. With a stereo system so non-standard it was sure nice to have this work without redesigning a mute circuit. I'm even going to integrate my radar and laser shifter to mute the system so I won't miss the alerts. The mute wire is a yellow wire in pin 7 of the 20 pin harness on the back of the stereo/cd player.

That is great to hear. I had hoped that the Levinson system had a mute point since we will likely eventually purchase an LS430. A couple of weeks ago, I hooked my Nokia car kit's mute wire to the drivers side male phone plug under the center console (front center pin) on my 2000 LS. (There is also a mute point on the LS phone harness in the trunk.) Last night I hooked up my wife's Nokia car kit mute wire to pin 4 of the 12 pin CD port (4th pin from the right on the top row) on the back of her Toyota radio (I installed a $14 Soundgate harness so as to have a wire to tap into since she does not have a CD changer). It is such a relief to have the radio mute when a call comes in - important since my new Nokia phone does not ring as loudly as the old one.
