So, this started about 2 days ago. No prior instances. My radio has always had the option to turn on without the key in the ignition. If I had it on while the car was running and I shut the car off, so would the radio. Now the radio will stay on until I manually turn it off. I noticed tonight that none of the buttons were illuminated and the screen itself was dim (my lights were on). Now, the radio itself is still completely functional. All buttons work, dials work, sound comes out of the speakers and steering wheel buttons work. I had removed the unit last night to remove a jammed disc and I don't believe that I affected anything as this was happening before. It's kind of as if the radio doesn't know that my lights are on. Anyone else ever have a problem like this?
