Hi everyone,
We have a 2006 H3 Hummer. Everything was working just fine on the entertainment unit until just recently. I had been playing a couple discs in the 6 disc unit the past couple days without issue. Today I tried to change it over to the radio. Nothing happened. I then noticed the red theft deterrent button near the ON button not flashing like it normally does. Nor the green CD button near the input slot not working. I can change the volume, turn on/off, and even repeat a disc. But none of the other buttons including eject nor load work. Any ideas? I did try taking out the fuse and putting it back in hoping to reset it. But that made no difference at all. Have not been having any issues at all with anything until today.

 

you might check the switch,band/cd. ive never looked at them but probably like the others like the 4hi,etc,small push button under the big cover.
or a loose connector.
