Lexus 2006 GX470 Radio draining battery when car is off on 2006 Lexus GX470

When the vehicle is turned off a clicking noise is heard through the speakers. The battery will evenually die. The only way to stop this is to remove the fuse to the radio. Any suggestions.

seek diagnostic to find your loss of electrical can do that too remove the fuse to your radio.
I know that the draining of the battery is related to something that is powered on the radio fuse because it stops when I remove the radio fuse the battery stays charged. Not sure what all is on that fuse?
