- Is there a difference between a PSP aux able and an iPod aux cable?
The aux cable for patching sound through a stereo? There's no difference. You should be able to pick one up for around $5 at any department store that sells electronics.
If you mean the sync cable for a computer, then there is a difference between gadgets--but it doesn't matter who manufactures them.
- Can I use an AUX cable to connect my ipod to my computer? If so, how?
You should just unplug the computer speakers from your computer and plug them into the iPods headphone jack. All the other ways would be complicated. For example, you'd have to plug your aux cord into the audio-input jack (if you computer's sound card even has one) and then get a program that can pick up the signal. Then you'd have to replay it.
- Connect an iPod through the USB cable or AUX port?
More then likely you have the same pioneer deck as i do or a little newer version, I say hook the USB cable up for two reasons (the same reasons i use mine) the Ipod can be controlled by the deck and also as a added bonus if you have memory sticks with mp3's saved on them you can plug the stick into the USB cable and play them, I like this feature on the pioneer decks saves on having Cd's kicking around my car. As for sound quality i don't see any difference.
