Schau mal in den Anhang!
Das ist das, was man mit dem letzten Update der Betriebssystem-Software-CD - Handelsname V32 - erreichen kann.
Schau mal auf die Seite 3 ... vom SIB 652102

1-1/80 für das MK1 ist tatsächlich der höchste SW-Stand

Hier ist die richtige Vorgehensweise für das Update: (seite 4)
For MK I, MK II, MK III, and DVD-Top NAV systems (except for the E65 and E66), use the following software loading instructions:
1. Turn the ignition to position 1 (terminal R).
Do not cycle the key or perform diagnosis while installing the new software. Make sure that the power supply is stable, i.e., do not switch on any electrical loads.
1. Activate "GPS-Navigation" and acknowledge the screen disclaimer by pushing the rotary knob on the board monitor.
2. Remove the map CD from the navigation computer by pressing the "Eject" button.
3. Insert the navigation software CD (V17.1 P/N 01 59 9 789 299 index "x" for Mk III without the split screen; V32 P/N 01 59 0 141 891 index "y" for all other versions).
4. Mark I System (up to 9/97 production):
After a few seconds, the BMW roundel will appear on the board monitor and will be "filled in" clockwise to show the progress of loading (approx. 4-6 minutes).
