I did indeed. Am going to spend today when I get home from work identifying the amp on cable. It must be part of that set of cables going to the ISO.
I think you need to remove the slim head unit from the fibre optic network. Because it tries to take precedence over the MOST decoder. I just left it unplugged and could check power was getting to it because the fibre optic light was on. You can't have both the MOST decoder AND the old HU plugged in. They clash.
Aiye I did, but when I have it all hooked up with the screen retention the stock HU seems to capture the events rather than allowing my aftermarket headunit to sort it. The only thing left for me after I get the REMOTE ON working is to do something with the upper screen, since it'll be dead, I wonder if I can run it strictly as either some crazy 360 camera setup that I've seen or just a reversing camera, but all without the stock HU This seems to know the REMOTE ON for the FF RR http://2ndrodeo.com/2007-range-rover-ampsub-install Am super tempted to throw all this crap out, get rid of the stock amp and stick in a small aftermarket one. But I've already sank like what 200-300quid into this now. |

You need a relay.

Hmm the screen retention kit came with one and since I butchered the out of it may as well reuse the relay. There's 100quud down the toilet to confirm a wire haha |

Are those pins on the original head unit plug? Also couldn't I hook it up to the ground provided by the aftermarket headunit? Wouldn't that be dead when head unit is off?

How's it going with the diagnosis? I've been looking online and from what I can see the OEM head unit MUST remain in the circuit as it is the system generator for the MOST circuit.

I'd just connect the wire Andy said to ground and see if it yields the results you want. But I'd be interested if your technique would yield both head unit and upper head unit working with the ordering.
