Ipod interface/integration for 08 Aspen?
 

Hello, I was wondering if I need to purchase the ipod interface for my 2008 Aspen. I have all the features on mine...i.e. Nav, DvD player etc.
I am just unsure how to get my ipod to work. Do i need to purchase the interface kit? or just the cable?
So far I just downloaded my itunes to cd's and then transferred them to my car. But what a pain in the a..Plus it doesn't show the names of the songs.
Advice anyone??
Also my nav has a plug, but if the ipod does plug into it, what type of cord do you need?
Thanks so much [align=right][/align]
