My Job 1 '07 does not have the aux player jack. That option along with the electric back window was added as "standard" starting with the Job 2's.
Here's your other option:
Take your tunes on the road! Now you can integrate your iPod® into your vehicle’s audio system. Just plug your iPod into the dock connector, conveniently located in the glovebox or floor console bin, to listen to your iPod selection through the vehicle’s speakers. Users can navigate your iPod’s menu while their selection - album, artist, genre, song, podcast, audiobook, playlist, composer is displayed on the factory installed radio. Users have full search control at the radio, and most applications also allow the use of the redundant volume up/down and seek buttons on the steering wheel. TripTunes Advanced also charges your iPod. Compatible with 30-pin iPods. Currently not available on navigation radio systems. A wiring harness (7R3Z 14A411 AC) is required and sold separately.

It's expensive. Two cables for a total of $300. Does not use an FM modulator, instead uses the Ford CANBus communications to add the ability to use factory controls. Mines on order and due end of the month. It's a new item in production.
