If you cannot cycle to an AUX setting, then your dealer failed to update your head unit. You need to have them do it again and do not leave until you can cyle to an AUX setting.
Cycle to AUX two ways:
On the steering wheel, press the SRC button, you will cycle from FM -> CD -> AUX -> FM; or just CD -> AUX if you are already on CD. (note, it will not cycle off of CD until a disc is playing, so give it a second or press repeatedly, then it will cycle.... back to FM if you do not have AUX)
[If you have at least InfoTainment II, (the green screen]
On the head unit, press DISC, select 'Disc Media' on the head unit, if you have AUX enabled, you will see two radio buttons, one for the dash CD player, and one for auxilary.
