I use an iPod all the time in my Jazz. It works just fine with just the USB cable that was supplied by Apple. The steering wheel controls operate the volume and allow track selection. I do not get a Honda logo on the display of the iPod, but I do get a message on the audio player that an iPod is connected to the AUX socket.
A good interface, however, it would have been even better if they had included a holder for the iPod or a division in the central console that would fit the iPod. As it is you just have to let it rattle around in the largest slot available in the console. I guess there ar so many sizes and shapes of iPod it may be somewhat impracticable to do this.
By the way, I have backed up some of my iTunes library onto CD and it displays and plays these discs just as it would the iPod.
Regards,
Jock
