Confirmed fixed. Static noise is gone

Now gotta figure out how to get power to the Roku from behind the head unit so I can keep it hidden

Just need to get the third row screen working and will see if the 100 watt usb charger is enough for the Roku

After that just gotta route the microphone and the chime speaker (I think I need the microphone?)
