I've been using my ipod connected to the AUX input for the past week or so with a $5 cable from Radio shack. The positives are that it sounds surprisingly good and as i mentioned it only costs $5 to get going. The downsides are that you can't control it using voice or the audio screen, just the ipod itself which takes your eyes off the road and there is no power to the ipod so after a few days you will have to remember to recharge it. I would reccomend mounting it securely and high on the dashboard if this is going to be your preferred solution. Comparing the PCMCIA adapter, it is much better integrated into the Audio System - even the Honda iPod adapter doesnt show you the name of the song or artist on the screen but the PC card does. You can also search for song's using the keypad as well as by voice. You don't have to worry about power and the steering wheel controls work as well. With a 4 GB card you can hold approx 100 albums (4 GB card = $125 at Amazon). 8 GB cards are much pricier but should come down in price. Unfortunately im a ipod and itunes fan so i've got a huge library of aac files but i will now be ripping to wma and leaving the ipod at home except for long trips. The PC card is a much better solution than the Aux port and even the aftermarket Honda iPod adapter - too bad i've got to use wma now but its well worth it for the integration with the rest of the system.
