Hey pokesju, not sure if you are still looking, but here is the thread:
http://avic411.com/index.php?/topic/36245-hybrid-40-avic-f900bt/
and the files can be located in either of the following torrents located on thepiratebay.se
"Pioneer AVIC F900BT F700BT 4.001 hybrid firmware"
or for a complete package from this thread:
http://avic411.com/index.php?/topic/22599-solved-the-formatmbr-sdmlc-and-mapdbinfo-error-0x0000-also-the-major-fix/
"Avic F update anc fix files"
I haven't included links to the files, but those are the titles of the torrents.
I'm hoping to fix
