Shami,
Kick ASS write up!
Couple points:
1) Rather than cut the defroster venting, just cut the back corner off the radio tray. it won't hurt anything at all and there's no risk of inadvertent 'slip' damage. I cut off all the trays for wire clearance when I do Avic installs. Never a problem.
2) If there's a hum, there's a loop somewhere. I theorize that a ground which is normally looped through the changer due to wiring -12v to mounting to the chassis is, of course lifted since the iPod is on no way grounded to chassis. To cure: You may try grounding the actual exterior of the stock head unit chassis. You may also wish to probe the harness for the -12v signal in the former changer/now iPod harness at the stock radio and ground it, thus simulating the factory loop.

If I have this figured out right it takes to parts from PIE. You will lose your cd changer. We can sell these for 59.95 plus shipping. The part numbers are X3 and X3 Frdw. It is a different part if you do not have a changer. Post up so we see how many of you need these.
