Bluetooth / CD changer hookup help please!

[WayOfTheGinja]

The guy I bought my Zed (e86) from didn’t seem to know much about what it had in the way of AV. So I started digging:

- Business head unit (easy one to work out!)
- Basic 6 speaker audio setup
- Some weird cheap Bluetooth unit spliced in behind the head unit, I’d found this on my iPhone’s bluetooth menu but never managed to connect - I cut this out (it was one of these - https://www.ebay.co.uk/itm/402123882312 ) Was wired directly into some power cables as well as a clip into the aux connector on the back of the head unit
- A loose connector behind the head unit - not sure what it’s for
- OEM Bluetooth (got the phone setup in the centre console and eventually found the ULF box after much trim removal - got the pin code now but still can’t get it into pairing mode)
- CD changer connector (wahoo) - plan on connecting this up to maybe one of these - https://www.amazon.co.uk/dp/B0773MX7BG/ref=cm_sw_r_cp_api_i_B68zFbRPZ3X6W

So my questions are:
- Any help getting the OEM Bluetooth into pairing mode (I’ve tried holding the phone button in the centre console for 3, turning ignition on them releasing after another 3)??
- What is the loose black connector in the photo from behind the head unit? Is it something to do with the OEM Bluetooth or the CD changer?

Looks like you are missing the outer sheath for that black plug. Might be on the one you removed. Those two plugs handle the CD change, BT and Nav sound so you will want to plug it back in.

Thank you! Yes, looking at the pin outs elsewhere on the forum those two wires do fit there once the outer sheath was reinstalled. Once connected I tried entering pairing mode and it actually went into the mode! Wouldn’t pair with my iPhone 11 though (entered the passcode from the ULF sticker and also tried 0000 - just said “Failed”) and now doesn’t want to try pairing again.
Well, I am a step closer at least!
