It came with software in a mini CD. This is the specific cable that I purchased and that I can confirm works: 2. Setup/Configure your OBD2 USB Cable Put the CD into your PC. I have an BMW INPA cable myself but used to install it on a XP laptop. Recently some forum members are asking is it possible to use it on Windows 7 system? If yes, how to? After much research, I have finally got it working and hope this can help any of you. I only used it on my E46 M3 (2004) and so I can confirm that it works fully with this car but I cannot guarantee if it works on other BMW cars.
