Parrot CK3000 in 2006 A4

I plugged the CK3000 into my Symphony II (no BOSE, no NAV)and ran a quick test last night and a few issues need to be resolved before I can complete the install. 1) No power to orange wire when ignition on - I'm planning to tap the windshield washer circuit since it's switched by ignition and seldom used. Any thoughts on this plan or a better alternative? 2) I plugged the yellow mute wire into the Mute #3(blue). The stereo mutted and phone set up was audible, but stereo did not say "phone" as I was led to believe it would. Is this as good as it gets with this stereo? 3) Lastly, phone audio was very loud and distorted. I understant a 5k resistor will tone things down a bit. Which wire do I splice the resistor into (also I could only find a 4.7k resitor, close enough?)? Thanks in advance for your input! Robert
