Which of the pioneer Ipod adapters fits the avic-n2?

The CD-IB100 or CD-IB100II

Silverdj:

I don't want to persuade you or taut you off the iPod adaptor. But, I wanted you to know that the adaptor you seek is a simple user interface for the head unit's screen. That is to say, there is only two benefits that I realized when I installed it in my N3; heads up display (I don't have to fumble with the iPod while driving), and it charges the battery on the iPod while in use. That said, the menus displayed are somewhat frustrating because it doesn't do a good job at navigating your way around the iPod. So, you may consider the alternate method of getting a RCA audio (red and white) to a single 1/8" stereo male jack to go from the iPod to the Aux input in the rear of the N2 'brain'. Use the N2 settings to activate the AUX and use it send the iPod output to the car audio. You use the iPod just as you would if connected to your head phones.
