sound system
 

I just bought a 2009 tucson and have some questions about the sound system.
How do I find out the manufacturer of my radio?
I tried to get info on the XM radio at their sight to help me learn about the XM radio, but they require the manufacturer name.
My owners manual says it's a PA710S, but doesn't give the name of the manuf.
Also, what kind of connector cable do I need to connect my mp3 player through the aux connection to play it through the radio?
