iPod unlocked with Dice Silverline?

[BrockWed]

Hey, I'm looking to buy an ipod integration kit and I think I have narrowed it down to the dice silverline... but I have a question that I have found conflicting answers too. I have a NAV X5 and I want to be able to use the iPod pick songs ect because I think using the nav is confusing because I have about 65gigs of music. On EAS it says "allowing the iPod to remain in "iPod UI" allows for a basic operation of the iPod's Clickwheel and can be switched to Enhanced DICE mode at any time." I find that confusing, can I control my ipod using the clickwheel? thanks!
