Hey guys!!

So I know there is a ton of info on installing an ipod on this site but i've been combing for a good hour and can't find what i'm looking for.

What are the options to install an ipod / iphone hookup?  I've contacted many dealerships and 99% are recommending an "adaptor kit" (p/n 8E0051444B ~$180) and one dealership is saying I need a full "integration kit" (p/n 4e0057785 ~$950).  I've got the nav with the 6 disc changer in the glove compartment.

I'm not concerned about maintaining the 6 disc changer or satellite radio operations - I just want a clean iphone hook up and am going to do it myself.

Has anyone installed or know which one I really need?  Do I need to remove the radio in order to perform the install?

I love the car but I hate how no one at audi seems to know these simple answers. 

Thank you in advance!!!
