Ext AV1 & iPod/AMI video?

[GlynH]

In both the 2011 & 2014 D4 MMI 3G+ when you cycle through the sources there is an entry at the bottom of the list for Ext AV1 or something similar.

Does anyone know where this particular input may be located?

I remember on my D2 (and D3 I think) you could buy an adaptor that had 3 phonos on one end for right/left audio and composite video and terminated in pins on the other.

These pins could be pushed into the multi-pin plug that went into the TV Tuner in the rear of the car to give you up to 2 AV outputs and one AV input.

Is this the same on the D4 or is there an AV input lurking somewhere I haven't discovered yet?

And on a related note is the AMI input capable of taking a video input?

I have an iPod connected in to the AMI connector in the centre console via its Lightning connector but it seems this is only capable of accepting audio.

The AMI lead itself has a yellow marker ring at the connector end and so I wondered if there might be a video capable AMI cable?

If not then all the more important to track down where the Ext AV1 input might be hiding...

Thanks & kind regards,
