Hello, my first post here. I just bought a used 2016 RZR 900 and it included an MB Quart soundbar 8. I can’t seem to get it working, as I press the power button and get no power indicator light or Bluetooth light. No Bluetooth that I detect from my iPhone. I checked the wiring harness connections and all seems correct (former owner claims it was installed by the local Polaris dealer). With the multi-meter, 12 volts show up on the pin for the orange wire (should I be seeing anything on the other 3 wires?) Any thoughts on what else to check or try for troubleshooting this? So far no response from MB Quart support.
