First time posting on the forum, although I have visited the site a few times in the past.
I recently tried to update my e46's navigation software, it has the MK4 so I downloaded V32 and put it on a disc, the disc loaded as it should and I was left with a black screen.
After reading up more, I discovered that this is expected behavior for a minute or two, but not knowing this I turned the key off and on again to try to "wake it up".
Eventually the head unit did boot back up, but with a really weird user interface. I used to have an interface like this one - http://i.ytimg.com/vi/Msgv0AWZ0us/maxresdefault.jpg
But now its more like this one - http://mukerji.s3.amazonaws.com/wp-c...00-800x600.jpg
The navigation option has disappeared from the main menu, leaving just "Computer" "Set" "Television" and "Monitor Off".
I have tried putting the navigation DVD back in the drive and rebooting, and also tried rebooting with the software dvd in there, neither will boot at all (though the red LED on the actual nav unit in the boot still flashes and I can hear the disc spinning).
I am going to try rolling back to V29 firmware to see if this saves me, but does anyone know of a fix to this problem or anyone seen it before?
Help would be greatly appreciated.
