The audio system just went out of my 2004 RX 330. I parked it yesterday and it was working fine but today when I headed out there was no display or sound. I thought it may be a fuse but they are fine. Is there anyone who has had the same problem and if so what is the fix for it??

 

I can't be sure as its been a while since I had my RX, but I think there are two fuses for the radio. One in the engine compartment and the one in the cabin. Check both of them.
