I have an 02 LS 430 with the basic stereo with cd changer. The other day I went to flip from CD to FM and nothing happened. Same with AM. I even pushed the mode button on the steering wheel and still nothing. The only functions I have is CD and Tape. Does anybody have any ideas on this?

 

bad tuner module in the trunk or it's disconnected?

 

Where about is this located? I can take a look. But I would think even with a bad module it would still do something when I push the button.

 

I think it maybe somewhere behind the passenger side of the trunk. Not sure though. You can contact sewell lexus. They are very knowledgeable.

 

I have the same problem. Still no fixes.

 

Have you Looked into the tuner unit? What have you actually done to troubleshoot?

 

I have done nothing but push my FM button everytime I get in the car. LOL

 

check the tuner!
