i have this double din head unit and am looking to buy an ipod to watch videos and listen to music. Anybody have a recommendation? Dont worry bout a price, just looking for one that will work with my clarion max675vd. somebody said it has to be a "3rd generation ipod"?? Anyway i need some suggestions.

PS: the reason i am looking for an ipod is because when i put a music cd in it... it reads: ERROR6 (meaning upside down cd) ummm NO. Yet it will play dvds like a champ. So im confused. hopefully the ipod will eliminate having to use cds.
