Although the sticky post is VERY informative on taking apart the AVIC Z series, all the pictures are broken and overall just years old.
Today I got bored and decided to try my luck and take apart the unit so that I can fix the plastic gear slide. It really only took about an hour to disassemble and that is ONLY because I striped 2 screws and had to dremmel them off.
TOOLS NEEDED
screwdriver bit kit, must contain the really tiny Phillips, Flathead and torx bits.
Dremel; ONLY if you're like me and stripped the screw heads.
STEPS
Follow this sticky thread EXACTLY.

Take your time flipping the locking tabs on the ribbons, they are in akward areas but very simple to do.
I have added the pictures to match each step.
