I bought a used 2001 BMW Z3 which has a "Business CD" radio.
I believe the radio is actually manufactured by Blaupunkdt.
The Serial number on the radio is Y8172841.
The code that came with the car has a 9 in it, and I can't figure out how to key in the number 9. Anytime I hit one of the preset numbers it enters the actual number I enter. I've already locked myself out of it once.
Thanks in advance for any assistance you might be able to provide.
