yes, that is correct

I did the hardware bypass. The video and navigation worked. However, there was no audio. I checked the speaker connections, the RCA connection, the Mute on/off, and still no sound. I disconnected the mute wire from the ground, the bypass was still working, but no sound. But, when I disconnected the parking brake ground, the sound came back to life, but the video and navigation didnt work. Where might have i gone wrong? I followed the directions as described in this topic...
