No your not dumb! My understanding is if you have AMI you need the Aux in plugged in (but not connected to iphone/media player) to activate the sound, see here:

Or are you guys connected the red/white composite audio cables the the x-carlink inputs then connecting its 3.5mm audio out to ami?
Why don't you guys try using something like this to bypass x-carlink for audio:

The AMI Aux input isn't necessary for audio, but it is necessary to "activate" the Aux input option (if that makes sense to you). In other words say you have an iPod plugged into the XCarLink unit via the composite Apple cable. Without the AMI Aux cable you will get video but no audio. With the AMI Aux cable you'll get both, but you don't even need the AMI Aux cable plugged into the iPod. It's weird, but it basically activated the Aux audio option in the "MMI" that will then allow the audio to go through the XCarLink unit.
I don't have mine yet, but this is the best info I can find from here
