    • technical

      Hi, install this unit for a friend, I'm a professional technician, but I muss say that the instructions are confusing, we could not get the backup camera to work, and Pin7 shows -12V rearview camera, so I thought that since it shows -12V it must be ground, cause +12V is positive, and now after I touch it to the ground, the unit has no sound, I'm wondering does this unit have an internal fuse,?

      everything works but no sound output. how can I fix this?

      thanks.
