My 2013 Tundra's stereo has now become selective when it wants to work... UGH. The stereo comes on and visually works, change stations, etc. but no sound. Sometimes when I get in and turn it on it'll come on and work fine and then after 20-30 min. it'll go out like a bad station even if I'm using the AUX. And sometimes it just won't have any sound from the get go and after 20-30 min it'll slowly sputter in the audio and work for a while. So what's up with this??????
