Adapting the phone buttons on wheel?
I've been thinking about this... for those of us that don't have a factory phone setup, is there any way to trick the car into thinking that one is installed?
This way, we could click the phone off hook to mute radio, then phone on hook to unmute.
I am handy with electronics so if anyone with insight can let me know how the system knows of the phone that'd be helpful.

From the spec sheet of the Audio 10, posted by Lockbuster on a different thread:
"Telephone Mute: Low active signal < 2 Volt."
Now I wonder if that means that the the voltage to the radio drops to <2 volts, or maybe does the telephone send a low voltage signal to the radio to mute it? Would it be feasible to reduce the voltage to the radio?

That unit also had dual color illumination (amber and green) that could be selected via a menu. That was neat...
