We don’t have the rear dvd in our qx80. The iPad been doing a good job keeping the kids occupied. But when we have the Qx60 with it, I was tempted to get what you’re requested. The setup below is for for iPhone.
Basically, you would need serveral items to have the iPhone play to the monitors.
- The apple accessory- lightning cable out to HDMI(needs power via usb)
- HDMI to RCA convertor (needs power via usb)
- RCA cables to the either front or rear aux(front aux can provide sound to car speakers, rear aux can only only get sound through wireless headset)
You can get all these items through amazon. It should work. Good luck with the cable management.
