So i installed a aftermarket radio in my 2005 a4. i bought the pioneer avh-4300dvd and it worked great for three days and now the damn thing wont turn off when i turn the car off? im completely lost in why? it worked fine for a few days and now i have to pull my radio fuse out to turn it off. does anyone have the wiring diagram, or circuit wire coloring for audis radio? i cant find it anywhere.

 

All i need to know is what wire on the audi harness is responsible for turning off the deck when you turn the car off? Been trying to figure this out for days!!! i know the red wire with blue tracer is the hot all the time (constant power) but what turns the deck off? if anyone knows anything? or diagrams please let me know, thanks
