Xtrons connector help

[creo]

Hello, so I purchased an xtrons unit for my e46 harmon kardon system with sat nav etc.

As an audio noob I'm completely lost with the audio connects, could anyone give me a hand? I bought the 6m cable extension loom as I understand I need this to utilise the HK system.

This is whats in my boot:

 

This is the connector going into the radio:



This is the radio connector on the unit itself:

This harness side 1:



This is the other side of the 6m harness:

This is the connections I have behind the front dash:

These are the audio connectors coming off the xtron unit:

Figured it out, I'll post details later.

So, for my install you need:

6m aerial extension cable
6m harness
Xtrons unit and cables

1) Back of the unit you can't go wrong, each plug will only fit into one socket.
2) You will get two bundles of connectors for which there is only one slot on the back of the unit. Use the one that doesn't have round plugs



3) Take the singular side of the 6m extension cable and connect it to the above


 

4) Take your BM Radio in the boot and disconnect the large connector



Should end up looking like this, ignore the yellow/green wires (This is an aux I had put into the stock unit).



5) Plug will look like this, remove plugs 1 and 2 from the back of the connector



6) Take the other side of the 6m harness (with multiple plugs). Take the connector I've marked 3 and plug it into the back of the radio unit you just removed the stock connector from



7) Take the connectors I marked 1 and 2 and plug them into the back of connector 3 you just plugged into the stock radio

😎 Take connector 4 from above and connect it to the stock connector in step 5, the blue bits do not block the connection. I thought they did which is where my confusion came from.

9) Unplug the aerial from the radio unit, it's marked in step 4. Plug the 6m aerial extension into the wire you just removed (nothing plugs back into the radio). Done
