By re-reading the complete User's Manual (which I downloaded for free). The directions on how to set AUX + SETUP to OFF were contained in this manual. I had been looking at the Quick Reference Guide (not the complete Manual) which came with the receiver.

If you happen to have the tool which allows you to remove your head unit from the dash use it. If not go to crutchfield.com and get one it's useful for any audio enthusiast. Once you have the tool pull the head unit out on the back of the unit there is a cable that is black with a blue connector tip. This is what you plug your cable that you got from your audio dealer into. As for making the cable accesible you may have to drill a hole in your dash or run the wire around and out the glovebox which is also common and suggested for your particular car.

Add Alpine's optional "Full Speed" connection cable and you'll be able to use the CDE-9872 to control your iPod. -Crutchfields website

This is compatible with first and second generation iPods touch.
fyi- if you have a mini-stereo aux in jack on the deck you can connect a ipod touch compatible mini stereo cable to the earphone jack of your ipod.

Had to take the vehicle back in to the repair shop. Good thing. Found smaller fuses blown and wires crimped behind stereo in dashboard. Told this could have been the original reason for main fuse failing. Works like a charm now, auto antanna raises, seatbelt light beeps and security system lights up. Stereo also works.

Try putting the unit in standby via the "SRC" button FIRST..., then press the menu button and cycle through to the "AUX 1" option and activate this....then press menu button again. When the unit is next switched on, you should have an "AUX" option accessible via the "SRC" button which will cycle through all of the availale modes ....standby-tuner-cd-aux etc etc.
