The below setup works well, I tether my phone to the Firestick, so you need a highish data limit or even better is an unlimited plan.

The Firestick was only £30



I also had to get an HDMI extender as the one provided is around 1mm long!



I then tucked the Firestick down the side of the driver's seat. You can still move the seat forward and backward etc and it won't crush it. I also zipptied the cables together but that was overkill, you can just blag stuffing the cables down the side of the seat.




The remote does not need line of sight, so the kids just point it at the screen and it works perfectly.




Few things to note:

• You can't view HDMI in the front
  
• It is best to enable to WiFi tethering on your phone within 30 secs of getting in the car, so the fire will pick it up. If you don't the fire seems to check every minute or so and connect automatically anyway.
  
• I used an app on my phone called "Force 4G" - its a good way of making sure when 4G is available you connect to it. You only need 4G for a few minutes and the fire will buffer most shows they are watching in full. I live in the sticks with dire signal and its not had any issues so far.
  
• I bought two cheap Sony headphones (£20) on Amazon, but you can get wireless headphones from BMW I think. I don't really fancy trusting my kids with £400 of headphones though!
