iPhone/Radio interface

[GasPasser]

Hey guys, I'm looking to install an auxillary adapter to my factory radio so I can play my music from my iphone through my radio and control it from the dash.

Here's a link to it:

USA Spec iPod Interface Connects your iPod to select 2005-up Ford factory stereos without the satellite tuner installed at Crutchfield.com

I'd rather not pay for the instal of this as I'm sure it's a pretty easy install, I'm just not sure on how to get the dash off to get to the radio, etc..

Anyone know of a write up where someone did something similar to this or to a write up on how to get the dash taken off to get to the radio? This is for a 2005 F150.

Thanks.
