I got in the car yesterday hit the button everything started to turn on fine then it a went black no radio no screen display. The fuse ended blowing so I changed that but no luck. The AC displays on the radio read out but that's it everything else is dead including the power sockets. I was thinking there is some kind of security protocol but it won't even ask for the code thanks

 

Did you check the fuse box under the hood for blown fuses?

 

did you get the problem resolved the mdx has the same problem especially in the winter ....the radio screen just go blank..check the mdx section and goodluck
