Hi there. I started having the exact same problem this week with my 01 ML system. Radio sometimes comes on after 10-15 minutes. Just went to my car and started it up-no sound. Tried the nav and got the voice, but still no music. My midrange control disappeared from the sound screen and no bars or control for bass/treble or fade controls. I sure would like to know what the problem is as I had no prior indication of a problem before this happened.
Does anyone have 20 inch wheels on their ls430? What kind of problems (if any) have you had and how long have you had them. Big wheel haters need not reply with all the reasons you despise upgraded wheel and tire packages. Just asking to hear from members who have had experience with 20"s.
