Ok, tried updating my NAV from v18 to v24. Downloaded and burned to CD v24. Turned on NAV ejected MAP and inserted SW upgrade CD. Screen showed loading Software...after that that's it, it seemed like it was rebooting itself, caught on a loop. Never showed a progress bar. I listened at the NAV CD and all it kept doing was spin for a second and stop. I let it do that for almost half an hour with no progress.

It took me a while for it to actually eject the CD, after hitting that Eject button hundred times or more.

Now I have no BMW screen. Nothing shows up. I got the v.23 one (can't find 22) but that still doesn't work.

HELP!!!
