Subaru Mcintosh 2010 How Can I Connect An Ipod To The Mcintosh Stereo In My Subaru Outback VDC?

How can I connect an ipod to the mcintosh stereo in my Subaru Outback VDC? - subaru mcintosh 2010

I have an Outback VDC with a factory-installed stereo McIntosh. What is the best way to add an iPod adapter, while maintaining optimum sound quality? Any advice on a marking clip and an elegant way around in the car will be useful. Ideally, I would be a clip that also serves as a mounting bracket as - I want to avoid having a cable hanging in the car when the iPod is not connected. Thanks
