I just set up my blue tooth this weekend. It was on the steering wheel - the bluetooth button. It displays on the radio, but the button is on the steering wheel and seems to be voice driven.
When the voice speaks say "setup". I found this out by telling the voice to "shutup" and it said, ok "setup". Haha. I can't find exact instructions on it. I came on today to look up blue tooth commands in the soul for more advanced settings.
Someone else I hope has more specific instructions for you.
