This past weekend, I received my NAV unit from OEM value and installed it. Backup camera and bluetooth work great. Only problem is the microphone switch isn't working. The mic works when I'm on the phone but that's it, no voice commands. I connected the red, white, and yellow wires from the mic/switch unit to the correct pins on R10. I also jumpered pins 12 and 18 on R10 per all the instructions I have reviewed. When I push the mic button though, nothing happens. Anyone know if I need to do anything with the remaining 4 mic wires to get the switch to work?

Appreciate any help!
