with the 07's you have to choose between either the 6 disc in dash changer or the ipod adapter. its a pretty annoying thing. you can not have both.

 

I have the OEM Ipod adapter in my '07 and it works just fine. It works in lieu of the 6CD changer. The wire is easy to snake out of the glove box and beneath the center counsul for hooking up wherever you want. A ProClip holder is ideal to use at it allows you to pull the IPod out with one hand, making it easy to choose a playlist before heading out on the road. The left control wheel on the steering wheel allows you to easily advance or reverse tracks. It's the ProClip holder that really makes the IPOD easy to use and read when driving.
