Hello, I was having an issue with my radio where the display on the screen was turned off but audio and all other functions worked. I read that if you disconnect the battery it would fix the display so we removed the ground off the battery and reconnected and the display came back on but now the radio and audio doesnt work. None of the buttons besides the clock button work and also steering wheel control buttons dont work. Checked all fuses and they are fine. Anyone have any clue what else it could be? It doesnt ask for a code or anything the only thing on the screen is the time and temp.

 

Ususally removing the battery and putting it back should help. Try few times. I also read this: "If you lift up the fuse box top, underneath should be a diagram of which fuses go where and what they correlate with. I hope this helps!"
