I have a 2004 RX330. CD player, which is part of the Mark Levinson audio system quit working. Other parts of the audio system works (i.e radio, cassette). I have 5 discs loaded. When I try to change the mode to CD, there is absolutely no response from the system. I tried the eject button load button.. NOTHING works!! Can someone help please. This happened after I took my car for a minor body repair at a local Lexus body shop and took it back, but they said what they worked on had absolutely no connection to the CD system. I am not sure how to proceed. PLEASE HELP!
