paring my phone with my Z4 2003

[retech]

I bought a couple of weeks ago a Z4 from 2003. Now I wanted to pair my phone via BlueTooth. I get to the point were I am being asked for the key pass. I have the original key pass, but when I put this in, it comes back with the message :wrong key pass.
Is there a way I can reset the system to factory default or to this original key pass number.
Thanks.

Nope can't reset - but if you lift the carpet in the boot away from the backwall you should be able to read it off the barcode on the back of the module. Should be silver, similar size to a shoebox, on the bottom left hand side.

There's no defaults, they're all pretty random.
