I have a 04 GT 6 Disk Mach.

Does anyone know where I can find instruction on how to remove this head unit.

Is it difficult?

Also is there RCA jacks on the back of the unit that can be used as AUX.

 

ok if you look on the front of the head unit you will see 4 little holes to the left and right of it. 2 on the left and 2 on the right. You can go to any automotive store or even walmart and pick up a set of DIN removal keys. They look like to metal Us you just stick in the holes and pull it out. it may take a couple attempts but thats what you do.
