Yep, thinking I'm making progress... just reconnected the battery and it was all systems go! - my steering wheel volume control even worked!
My observations so far: I'm using Connects2 kit, came recommended, yet so far I've had to snip 2 unused wires (can be reconnected if I change manufacturers) and join a wire to one of the stereo power outs - specifically for the steering remote. It even had a little label on it
I'm also using their analogue aerial kit, even though I'll be fitting a DAB tomorrow. My stock head unit had 2x fakra adaptors is it, and this new cable only has one. I'm guessing its personal preference which one I use? Anyway, how do I power it up, I'm guessing I use a spare 12v from somewhere on the harness? An ideas?
@ds2601 - how have you installed your DAB/Bluetooth mic. I'd be interested to know how you fitted it, specifically how you routed the cables.
Thanks.
