I adjusted the volume on the unit to about 95% and don't notice any noise when there is nothing attached when it's on. I tried this with both the car on and off (key turned). I haven't scoped it or anything but am still searching for the right sweet spot of volume on my cell phone going into the box before there is clipping. I think the limiting factor is the really crappy 33 year old Asi radio in my car but I just don't want to swap it out with a modern unit.
To combat noise, you can twist the power lines, put a small cap across the lines, or use a quality shielded cable between your iPod/cell phone and the iSimple box. If you're hearing alternator whine, a cap can definitely help with that but you'd probably be better off spending money on better spark plug wires.

Mine definitely doesn't make that noise. I'm set to 87.9MHz and don't have any location stations near there. With the preamp on or off (there's a button for this on the Asi radio) I can hear some noise like static pops and very quiet hiss with the stereo cranked to 11, but nothing like what yours is doing.

Drained and cleaned my fuel tank for a second time. Was still very clean from the first time but a small chunk of the old boot had dislodged from somewhere (way at the back, I imagine - where I can't reach)
Unfortunately when I went to grab it, it turned to powder. So I ended up cleaning the whole thing over again. I wish I had arms that were a tiny bit skinnier and a tiny bit longer.
