Need Help

I have a GPS unit with an audio output (stereo) and a car stereo with a
GPS/Phone input. The GPS input is switched thru the ground, when the ground
is opened the audio mutes and the GPS audio is played over the speakers.
How can I create a switch the senses the audio, opens the ground and allows
the audio thru?

Any help is appreciated.
