Help with radio code

[bluedevils]

Call up two dealers and got nothing, please help me with the code:
serial #BP0273 1 9943921 (another number is 7 640 273 643?). It is a CD43 unit that I am trying to install in my 91 381is.

Both are not BMW part numbers. Need to half proof of ownership as well so they will give you the unlock code. Most charge $20 to look it up.
