Nevigation Retrofit Addendum Information

Contributed by: Geoff Allison

To those who have retro-fitted navigation to an X5 using the
official BMW

retro-fit kit, part number:

65 90 0 136 497

I can assure you there is a factory mistake in the BMW supplied wiring

with this kit.

After I installed mine some four months ago all worked perfectly it

but then I decided to check the service menu settings (not part of the BMW

instructions funnily enough) and I noticed that in the service menu, that

under the "sensor" menu I did not get any wheel sensor readings. I did get

reverse/forward and Gyro etc.

So I checked and checked again the connections - all as specified in the

instructions, I tried a different NAV computer (a MK III, I have a MK IV)

and all was the same.

I e-mailed this group and you (some of you) told me that this sensor

should read zero when still and figures like 289 when moving (goes up with

speed), not so in my car!

Then I looked at the wiring diagram in the instructions again, the DFAHL

wire (the one we need) goes to the "Bordeaux" coloured plug on the NAV Mk

III or MK IV computer/disk system on PIN 11.

I then looked at this web site:

And in the E39 the DFAHL wire is connected to PIN 10 of this plug (it is a

brown wire with a red stripe) and PIN 11 is marked as not used. I then

the E38 retro-fit kit instructions from BMW on the Web and the circuit

diagram in these instructions also showed PIN 10!.

So I moved the wire from PIN 11 to PIN 10 and now it works!!! I get sensor

readings and in tunnels the car still moves along the road, great stuff.

So to all those who have used this kit, please move your pin!

Regards, Geoff Allison

P.S. This fault is not obvious and can only be detected in the service

when you are on the move, but correcting it does improve the NAV slightly.
