The only difference in the adapter loom is it has Pin 13 present 'AR'...?
See pic

 

Pic below is the mini bluetooth thats part of the adapter, which is powered to pin 15 in A block which is power and pin 12 ground so its getting power, the other 3 pins go to Aux L & R and Aux Ground.
Cant see why this is not working????

 

I dont have a loom coming from my car for that block which is for pins 17 to 28 are in f-bus and rsa etc etc.

 

The little black box powers up when connected and flashes blue light when your pairing it once paired it stays solid blue and on phone says connected for phone and audio, on the adapter loom the little bluetooth box goes to pin 31 - Aux L, 32 - Aux R, and Pin 38 - Aux G. which should go to mp3 socket in cup holder so this should take the place...???

 

The pins you have circled in red are actually these ones, which are the wrong ones.

 

I think you are looking at the wrong pins. The diagram shows connection pins where I have circled and that appears to be empty.

 

It's not clear what you have actually bought, it looks like it adds a microphone for you and plays calls via the head unit. But it is not clear whether this adds Bluetooth or simply works alongside the Vauxhall Bluetooth module. One part of the description says it works alongside of it but other parts it supports Bluetooth itself.

 

I thought you had bought the Vauxhall kit but it looks like you have some other gizmo.

 

And what does PH + and PH - for ?

 

plug and play should be...??

i thought this took over the aux input i have already for mp3 which is near 12v socket

 

It needs coding into your vehicle by changing the variant coding, otherwise it won't know its there.
Yesterday is done with suitable diagnostic equipment.
