norm, here's my take on things, from someone who just bought a car. i preferred NOT to have pdc (just wouldn't use it much and agree on the asthetics), but did want the m-audio as i think most buyers would rather have the top audio in this vehicle. as for the shades, i would've rather had them but the car i found (used) didn't and i decided that one option wasn't enough to sway the other good things about the car i was looking at. if i were ordering new, it would be m-audio and shades (i live in california) for me. good luck with your investigation!!
