It has a ipod connector ( http://salestores.com/panaso722.html ) that i am considering buying that will control ipod functions on the head unit. my question is "can i play pandora thru it?" im interested in internet radio, not really ipod functions...."btw..i have iphone 3gs

 

It should connect an work with the Ipod interface if not you got AUX input, See below.

If you look at the specs "2 volts audio inputs and outputs "

Yes, it will.
