Gosh! To think of all those who chucked out their Businees CD's for an aftermarket head units,LOL!. I myself almost dumped RM150 to a shop that claimed to be able to "reprogram using special software" to have my frequency corrected. Dig this simple DIY step-by-step taken from Bimmersport.co.nz. Happy "reprogramming"! :-
Here's a useful 'How to' for BMW fans:
HOW TO CHANGE JAPAN RADIOS TO NZ FREQUENCIES - WITHOUT A BAND EXPANDER
Factory fitted BMW radios from around 2000 onwards have a 'world tuner' inside them. The same radio can be used anywhere in the world.
The radio can be programmed to operate in JAPAN mode (FM = 70-90), or in OCEANIA or EUROPE mode (FM=87.5-108).
They also do a USA and CANADA mode but that's not useful here in NZ.
BMWs imported from Japan have their radios set to JAPAN mode (wonder why?)
These can be readily re-programmed to NZ frequencies as follows:
1. Switch on radio
2. Within 10 seconds, press and hold down the 'm' button until the serial number appears (takes around 10secs) to enter the radio's service menu.
3. Use the + or - buttons to cycle through the menu settings until you see AREA JAPAN or just JAPAN (varies a bit depending on radio)
4. Use the 1...6 buttons to select either OCEANIA (or OCE) or EUROPE - both are valid settings for New Zealand - see below for differences.
5. Switch radio off to store the change
Voila! Your radio has now bee reprogrammed to receive NZ FM frequencies!
Also, the cool RDS features will now be available.
Differences between OCEANIA and EUROPE modes on an E46 Business RDS radio (other radios may vary slightly):
a) EUROPE has LW, MW and FM. OCEANIA has AM and FM only.
b) OCEANIA shows ST for a FM stereo station; EUROPE doesn't show anything for stereo or mono FM stations.
c) EUROPE has the softkeys set to RDS and TP; OCEANIA has RDS and PTY
Which ever one you choose - OCEANIA or EUROPE - is up to you, they both work.
