Use the Main Audio Harness plus the Nav connecting Lead adn the Supplimental Navigation Harness like it is shown in the EBA instructions, or use a combined harness from this guy you found.

The yellow/red wire on pin 1 of the 6 pin connector of the Nav Connecting Lead (X1310B) is for the the DFAV-L signal (that is speed pulses from the Left wheel rotation senser) and this is tapped off from from the ABS control module connector X1170 at pin 35. You can splice into this yellow/red wire without removing the connector from the ABS module if you just get to it located on the fire wall just behind the glove box.

In my schematics it shows that the Nav connecting lead should also have a Yellow/White wire on Pin 2 which would be for the DFAV-R (right side speed pulses) tapped off from pin 18 of X1170 on the ABS control module. I am not sure why this is missing on yours, however as I have said, my Nav works fine without these signals, so maybe the E39 wiring deleted the right side speed signal and only used the Left one.

By the way the wire on pin 1 of the Nav connecting lead 6 pin connector should be white with a yellow tracer line not a yellow with a white tracer line. It is amazing to me that BMW used two wires with inverse color schemes in the same connector, but they did, so be sure you are looking at them the right way. The first color given is the main wire color overall and the second color is for a tracer line that runs the length of the wire and the third color (if used) is for horizontal stripes that run around the wire.

The retrofit kit that the guy you know of is using a harness that combines these 3 harnesses into a single harness. The reverse logic wire is a different color, but as long as this Blue/yellow wire finds its way to the Burgundy colored connector that goes into the Nav Computer on pin 1, it will work fine. I don't know anything about this combined Nav retrofit harness that you found, but if it is capable of connecting all the right things, then it is probably going to work fine.

I know that the X-5 harness that Martin recommended included the Nav Connecting Lead into the main harness, so it was already one step toward a combined harness. Perhaps the guy you found created a single harness or found one from a BMW car that provided all the wires needed in one?

I hope this helps, good luck
