Yep
like this courtesy of Andrew although V21 should also work
"
I now have a fully working 16:9 display with fully functioning info and select
buttons!
You need to download and burn a v21 firmware disk
http://www.e38.org/nav/v21_1_CloneCD.rar
turn on ignition all the way just before she starts, start up the satnav
put it in map view, remove map disc and put in recently burnt disc of version
21(i burnt mine at x1using cdclone)when the software had finished before
the ok screen i turned on and off the radio(not sure whether this makes a
difference or not)for about 3 secs, put my map disc back in whilst the ok
screen was still there, when i pushed the button to OK i turned the radio
on and off for 3 secs or so(not sure whether this made a difference or not
or whether the firmware has the necessary codes already in the software!)and
voila push info and you have tp,rds select tp and keep it pressed and you
get a radio version number. push select and you get radio sensitivity etc
in cd, all the ussual forward back etc and in tape mode dolby b c etc(you
get my drift anyway. Then i updated to version 27 with rover splash screen
doing the same radio on off bits and it all works, perspective split screen
etc.
