I really want to play tunes from my iPod in my car. I can use the casette player adapter in my IS. I was hoping to have a casette player in the G35 Coupe, but the 2006 model doesn't have it! FM transmitters are so useless here in the Bay Area where there are many radio stations. I found an unit that directly connects to the tuner on the back and gives an audio input from Pacific Accessory Corp. It's called AAI-NIS2. It sounds great! I don't have to bring in lots of CDs to my car. I have almost all the albums that I have in my iPod.
