Remove the four 6.4 mm Phillips #1 screws holding the adapter to the outer case.

Only remove the following screws if you are planning on taking apart the iPod Adapter later on:

Two 6.4 mm Phillips #1 screws near the center of the adapter. These screws have built in washers.

One 4.0 mm Phillips #1 screw near the center of the adapter.

The iPod adapter should now be separate from the upper casing.
