Duncan that would be a great help.
Ceedy reckons the box isn't needed to use the steering controls with the unit I have. Does that sound right? The instructions I got with the unit show a screen where you press one of the buttons and tell it what that button does. I believe these are known as learning systems?
Quite possible but I don't know as I've not had much experience of the kind of aftermarket system you are fitting
If that is the case I won't need the interface and therefore won't need the bracket either.
yes but to be fair to you at the very least the interface shoould be part of the kit you are selling. Ideally so should the harness, as it will devalue your kit if it doesn't have it. Depends what you are looking for for the bits, but PM me with an idea n=and I might use them as a backup for my car if bits fail (or for a test becnh I'm planning).
So next question - if those wires are for reverse etc where are the steering wheel wires? Actually scratch that, they're obviously the ones that went to the connection block for the interface? So which wires from that do I connect to the 2 wires for steering controls on my head unit?
yes but they are also in the BMW connector. I'll dig out the colours and get back to you.
Last question Duncan - if I connect the unit via an adapter to the BMW plug will I have sound and power to the unit, but no HK?
If so I can at least get it fitted in time for my jollies and then work on getting HK sorted when I get back.
Thanks for all your help
Yes, that's the easy way. The half of the connector with the sockets provides battery power, ignition, and the connection to the speakers in the four doors. The twisted black / colour pairs (four pairs, eight wires) are the speakers. LGW is accessory, PK is permanent, B is ground.
