Hi. I'm from Poland and I've just bought 2005 E46 330Ci from Japan and I've just successfully managed to change FM radio frequency range to OCE, with the help of instruction from this thread
But... I still don't understand why my MK4 radio displays completely different menu (strange interface) than EUR BMW versions. In my trunk I don't have DVD reader for Navigation. Just two "modules" visible: HDD NAVIGATION SYSTEM and PC CARD slot. Can I somehow upload new MK4 EUR firmware via PC CARD/SD Card emulator to get "normal looking" menu?
Here is how it looks: https://imgur.com/a/lR529Ua
