Can someone provide a link or viable source for V21 software? Thank you!

Now I have downgrade and uppgrade and the info and select button is working again but where is the split screen for the radio. Is it not possible to get the split screen together with the function of info and select button´s?

can anyone help me..
i have a 98 540

i upgraded my screen, nav and tv tuner to a 16:9, MK iv and a
dual output 16:9/4:3 tuner..

i had a prob with the select/info button so had to take it to a dealer to code..

after that i upgraded my dsp amp and also my radio to a bm54 ( the one i took out was a bm54 but with round pins)

anyway i had an option called nav-min which i love... but i think since playing around with navcoder i have now lost that option and for the life of me cant get it back.. tried navcoder and also taking it to a dealer.
i beleve the nav-min was a feature of the bm54 aswell as the aux input, additoons radio bands, true split screen etc. (which i do have all of these.. its jsut the nav-min option i cant get back)

then i press info i get the following (from memory) TP, TP-min, RDS, audiotext ( as i upgraded cd changer to a newer mp3 one)
anyone got ne ideas?

Can't seem to find solution anywhere. Running V30 OS on MkIV unit and noticed i was not getting use of the info and select buttons. Downgraded to V21 doing the radio on/off thing mentioned and buttons now work fine, but now lost split screen on radio which DID work before. Upgraded back to V30 but still no radio split screen but info and select buttons still work. Tried this time to downgrade to v26 and got radio split screen back but lost info and select again.

Like the poster above, is there no way to have use of split screen on radio AND info/select buttons working?

MkIV unit was an upgrade from a CD nav unit previous as i understand this may be an issue.

Can anyone advise?? Driving me nuts.

You CANNOT have radio split-screen and INFO and SELECT buttons working. It is one or the other.

BMW never intended the software to work with split-screen radio on a 16:9 display.

Sorry.

You mean without BM53/54

i have split screen (using a bm53/54) and my info and select buttons work fine..

although ive lost the nav-min option
