I just installed a Denison IceLink Plus into our 03 Lux, and I noticed a background buzzing type noise from the stereo... it's quite strange, when you turn the volume down to "-", the noise disappears, as soon as you turn the volume to 1 the noise appears, and remains constant in volume right up to max volume (this is obviously with no music playing). If it was just general background noise from the stereo it should increase as the volume is turned up... I don't know if this noise is common to other Euro's - or even if it existed before I installed the IceLink - I tried disconnecting the IceLink, but the noise was the same - I can't think I ever sat in the Euro with the engine off and the stereo on very quietly before I was installing the IceLink. The noise appears regardless of input selected - radio, CD or CDC. It's got me completely baffled, and while it isn't very noticeable - I assume you can't hear it all whilst driving and it get's drowned out by the music once you get to 6 or 7 volume - now that I know it's there it's gunna bug me...
BTW, the IceLink is very easy to install, the hardest part is getting the compartment below the stereo out... I'm happy with the IceLink too, controlling the iPod from the stereo is pathetic as I suspected, but it works nicely controlling the iPod from the iPod, and allows the steering wheel buttons to track skip still (as well as switching off the ipod when you turn the stereo off).
