Look up the parts that are offered from Dice Electronics.
http://diceelectronics.com/uni-150Or if you want to go bigger
http://diceelectronics.com/fmrds-usb-proThese are THE best aftermarket iPod adapters for OEM stereo systems.
P.S.
You will also need antenna adapters. (They should sell these EXACT parts at Best Buy. Best Buy is a Metra dealer. These are the exact part numbers you need.)

Just some additional information. If your vehicle has RDS (easy way to find out is to play a major radio station, and see if the Song/Artist names come up on the OEM screen).
If so, when playing your iPod off of one of these Dice parts, it will show the song you are playing from the iPod, on your OEM screen.
Another thing, the 2nd version comes with a USB port which means you can plug a Flash/Thumb drive into it and play music. It also comes with a remote (The 1st option does not) which WILL change the song on the iPod to the next song. So you can leave your iPod on shuffle in your glove box is desired.

More info that I feel you should know before I go to bed:
What these do is create a very very strong FM signal, nothing like those transmitters from Walmart. They are so strong that they need to be hooked up to a switch, because with it on, you wont even receive any other radio stations. Its so strong that you get the quality of a CD. And it charges your iPod!
