Ok so I've been asked to make a guide, bear with me as I’m usually useless at explaining things!

I don’t have blue & me in my car and was getting fed up with having a wire hanging about for the AUX input, so I pinched an idea from my wife’s Corsa.

I bought 2 adapters on eBay one to go from the HU which split into red and white cables. (You may need to adjust the order the cables are in at the end of the adaptor)

And then one which plugged into these with an input on the end.
