I just got in from installing mine. On the earlier Q, the input is a 5 pin. So Audio L+, L-, R+, R-, and 12V trigger. I used the adapter I made for my other one, and just hooked the blue wire on the AudioPipe adapter to it. It outputs about 12VDC whenever the adapter is outputting audio. So in my case, opening my phone screen (which makes a little bit of a noise) triggers the radio to switch over if the Bluetooth connection is active... even if I'm not playing music at the time. I can avoid this behavior by turning Bluetooth off in my phone's menu, but it'll take a bit of getting used to. Sound quality seems good... I noticed a tiny bit of engine noise that I'll try to get out with a filter when I can find it, but nothing too obnoxious.
I wired the AudioPipe to the cigarette lighter wiring (same as my old NEO MP3 player) so it's receiving power any time the car is on, with the ground wire to a screw on the chassis. On the older Q there is no CD button on the head unit... only one for the tuner, and one for the tape deck. The deck just switches over to the auxiliary input when the correct pin sees 12V, and allows the other switches to work (tuner or tape) if there's no 12V on that pin. I'm not sure how your 94 setup works.
