The Cassette Tape Adapter is useless for your application.
Anti-skip is a feature that works within the CD Player, and unless you can turn it off/on, it should work no matter how you plug it in.
The Cigarette Light is your power source, so unless you use batteries in the CD player, you will need it hooked up,
The best way to interface a portable CD (or other music device) is thru the USB port.
Old CD players do not have USB ports.
My guess is that you may be able to find/use a cable from Headphones Jack (on the CD Player) to the USB port (in the Passport).
My other guess is that it probably will not sound any better than simply uploading music to your phone...
I would echo, what was told to you above - LOOK FOR A CD PLAYER WITH A USB OUTPUT (PORT)...
Thanks for all of the responses.
This is the only CD player with a USB output that I could find that's compatible with the Passport, and the reviews are mixed. Some people say it stops working after a while.

So if using an old portable CD player, you think using the headphone out on the CD player, with this adapter, to the USB port, could work:

This is for a family member, but right now that person is deciding between the simplicity of a CD player, or ripping and uploading music to a phone / iPod.
This person is not an audiophile, so they would be mp3s.
Though I am just asking, because I want to understand your comment about sound quality.
Do you think using a headphone out jack into the Aux port sounds any better or worse, than headphone out to 3.5mm to USB adapter to USB port?
