4: Disconnect the wireing from the Radio Module and
remove from the dash by pressing down on the release
hook and pulling toward you.
5: Route the speaker wire connection on the Nav
interface harness up to the area below the dash cover.
If there is a center speaker unplug the speaker
connection and connect the speaker to the harness,
then connect the speaker harness to the nav harness,
this is a T-Harness and requires both connections. If
no center channel speaker is present route the cable
to the left front speaker and connect the same way.
