as far as auxiliary factory inputs you actually do have a couple of options:

Aux inputs:

Ipod inputs:

ISimple ISAS71 (comes with harness)

PAC Audio iPAC-OEM w/ AB-CHR99 harness

the only difference between the ipod inputs and aux inputs is how it hooks up to the ipod. The aux interfaces use the headphone jack for any ipod or mp3 player. The ipod interface connects to the 30 pin connector on the bottom of the ipod/iphone, and will also charge while the car is on. The quality of the music with be the same no matter which way you go. All these parts retail between $100-120, but you would probably be able to find them cheaper somewhere online

 

Sweet thank you
