1) what version are you running? 3-1/31? 3-1/50? 3-1/63? something different?-It is running 3-1/30.

2) IF your display says 3-1/20 thru 3-1/31, you will need the key CD that is required to update the software past V17.1(3-1/31). Otherwise your screen will tell you to insert version 17 or the key CD.-Does not ask for The CD key. My understanding is that insert the Update CD first then the key.

3) If you are running 3-1/50 or 3-1/63(the last version for the Mk3) then (re)loading the V32 disc MAY reload & reset your software to 3-1/63. I don't know for sure. I just upgraded my software from 3-1/20 to 3-1/31(v17.1), then I loaded the disc that came with the key CD that brought the software up to 3-1/50, from there I loaded the V32 disc and it finished upgrading my software to 3-1/63.Running 3-1/30.

4) do you have any software discs? My used 2001 did not come with any and had never been updated even during the 3yr lease period of the 1st owner, which it should have. Everything I learned about the nav has been on this website. My Mk3 did not read any of the clone CDs I made from downloads, so I bought the CDs from my Idaho dealer. At first it was very confusing as BMW uses 2 version numbers to describe the same thing (v17=3-1/30, v17.1=3-1/31, and supposedly, v22 thru v32 will give you 3-1/63)--I have the latest version of the mapping CD for the midwest I bought from the dealer.
