For those with an AP1. The USASpec PA11-HON iPod Connector will plug and play into my 2000 OEM head unit. It WILL work using the iPhone 4s and WILL charge it as well. Everything is controllable using the OEM dash controls. It's as simple as removing the radio door, 4 screws, and plugging it into the back of the head unit, and choosing where you want the cords to go. Literally took me less than 10 minutes.
