I found this on the 'bmwnav' group on Yahoo Groups (originally posted on 9-26-02 by 'cfoote2667'). I thought it might be useful to some people here with Nav. I had mine updated today at Crevier.

------- BEGIN PASTE -------------------------------------

There is not much to say here....except that they talk about 9/2001
vehicles being the only ones that can use the v.20 CD. We know that
to be incorrect, as all 2001 vehicles in the BMW lineup had the MK
III unit to begin with. Therefore, I have no idea what BMW is
getting at -- I have the 'split-screen' software on my 2001 without
any problems. But, here's some info for what its worth....

Navigation Operating Split Screen Software V20.0

E46, E39, E52, E53, E65, E66, E85

From September 2001, all vehicles with "split screen" navigation
system will now be using Navigation Operating Software V20.0. Except
E65/E66 vehicles prior to 9/2002, which will continue to use Nav CD
V19.0. If Nav CD V20.0 is loaded into an E65/E66 prior to 9/2002 the
CIP program will prompt you to "replace the Navigation Computer". Do
not replace any parts. Reload Nav CD V19.0. All other non "Split
screen" navigation vehicles produced prior to September 2001 will
still use the Navigation Operating Software V17.1 and cannot be
updated with V20.0. For information regarding Software V17.1, refer
to SI B84 11 97 dated September 2002.

Note: When programming an E65/E66 from 9/2002 production, Split
Screen Software V20.0 must be used in conjunction with CIP V3.0 or

Changes/Improvements for Mark III system from September 2001

The "Set" screen shows the software/hardware version in the form
of "3-1/60" or "3-2/60". The numbers have the following meanings:
first digit 3 – indicates 3rd generation navigation system (MK3);
second digit 1 – indicates top navigation – Mk3c color screen, or 2
indicates radio navigation – Mk3m monochrome display; the last 2
digits 60 indicates the software status of the graphics component in
the navigation computer (MMI) Machine Man Interface.

Split screen display is possible, i.e. it is possible to split the
display of the on-board monitor and support map routing together
with the direction arrow routing.

It is possible to set whether the cursor moves on the map (same as
V17.1 and older software versions) or whether the cursor is
stationary and the map moves.

"Zoom function" for destination entry.

When entering the destination, the directory is constantly shown in
the display, making it possible to change the directory faster.
Further information is contained in the owner's manual for the
navigation system, which is provided with the vehicle.

To load the new software in E46, E39, E52, E53, E85, follow the
procedure below:

To replace the navigation computer:

When replacing a defective MKIII computer, a configuration signal is
