How to disable rear audio control on 2016 Expedition

[BakoB]

I want to be able to disable and enable the rear audio controls on my 2016 Expedition but cannot find anything in the owner's manual or online about how to do this. On older models you could hold down the 3 and 5 presets. That doesn't appear to work on the 2016. Anyone know how?

I have a 2015 Expedition Limited 4x4. I do not know how to disable the rear audio controls.

However, I am curious - why do you want to disable the controls?

I only want to be able to disable them when the kids riding in the back seat won't stop messing with the controls.
