I have a BMW MK3 sat nav unit which was on version SW 3-150.

I wanted to upgrade my firmware and used a download from www.simplymini.info with v26 files (this should take a MK3 to v22).

I popped in the CD, watched the "loading software" screen before my screen went black, and is now permanently black. After some struggle I managed to eject my CD but now I am left in eternal darkness on my screen

Can anyone help me?
