The problem I have is sometimes the volume up/down is screwed up. When I want volume down, it goes up. If i'm on the radio, volume up is switching to the next station. Anyone has this problem and how can I fix this? it's very annoying!

 

I have the same problem in my 03 TL. There seems to be a short with the buttons as sometimes they work fine.

 

there is fix for it. contact your dealer. its a common problem
