Installed in my '08 S-type (w/ nav). When using the AUX1 setting (controlling the IPod itself, not thru the radio buttons), I get a distinct whistling noise at the start of each track. It's a short, rising, electronic tone that actually sounds like a drive spinning up.

I though I would just put up with it, but today I got that sound right in the midst of a quiet section of some music. = bad.

Any ideas? Would the latest firmware help? Yes, my plugs are seated tight and the unit is installed on top of the XM in the trunk.

Thanks in advance.

 

im tryna find out what this is myself....i got the whistling noise at the beggining of each track as well followed by a momentarty "hiss" during playback. now i dont get ANY sound at all. but the ipod still plays....wth? :angry:

 

I put together tech support email to peripheral.com and I'll post the reply when I get it.
