Disco 3 - amp remote wire for Android head unit

Hi folks

I have searched high and low but can't seem to find a solution to my problem.

I have installed a Android stereo with a MOST Converter. The stereo starts up and all steering wheel controls work perfectly. But there is absolutely NO sound coming from any of the speakers!

I think I need to connect the amp cont wire to a remote wire to turn on the factory amp, although after searching everywhere I cant work out which wire from the car I need to connect the "amp cont" wire from the stereo. Can anyone please help me!

Thanks

J

You need a relay.

Pin 30 to earth
Pin 85 to earth
Pin 86 to android remote wire (typically blue)
Pin 87 to landrover trigger wire

Interesting to know. I'm about to fit a MOST adapter and didn't realise I needed a trigger wire.
