Very cool, thanks for the feedback, I'm definitely no electronics guy or audiophile so I appreciate it. Where did you wind up hooking into the circuitry for the audio input? I considered a connector with a built in switch but I think at the time (this was almost 10 years ago) I wanted to keep my iPod connected all the time and be able to cutover the sound with a simple switch. I think I had plans of placing a small switch on the face plate of the radio for a more polished look but opted not to modify the aesthetics of the unit.

To be honest I never used this system much, I was never enough of a music buff to bother so I just wind up flipping on the radio
