How did you guys install the ground loop isolator on your is250/350? It would be greatly appreciated if you can provide a step by step process. I need this information in order to reduce the static noise that my Zune is creating.

 

Step 1: Buy one.
Step 2: Plug it in (one end to media player, the other to the "aux" input, you need to split the stereo minijack to RCA usually)
Step 3: Play.

 

What does this mean?

 

Buy one and it will be more obvious to you. It simply sits in line between the aux port and your media player. I bought one from Radio Shack, which comes with an RCA to mini adapter. I need to buy an addition RCA to mini jack adapter for my iPod.
