Hi,
I think I may be able to help you.
Turn the radio off and then back on.
Keep "m" pressed (10-12 seconds) until it shows you the serial number of the radio. This "m" button is the same button that you use to manually tune the radio frequency, and should be inbetween the "<" and ">" buttons.
Once it shows the serial number, you are in service mode.
Now you can cycle through all the different service mode options using the "+" and "-" buttons.
Cycle through until you get to the option that says AREA: JAPAN
Now you can use the "1" button to cycle through the different areas, so choose Europe or Oceania.
Thats it! Now press "<" or ">" and the radio will automatically restart, and the frequency band range will have changed from 77-90 to 88-108.
I have done this in my OEM E46 business CD, and I am hoping it will work on your E36, because although BMW changes the fascia between the two generations, the software update only accounts for very little change between different versions.
My car was imported from Japan, and due to the lack of this knowledge the dealer installed a band expander!
Apologies if this does not work on the E36, but it might be worth a try
Good luck!
PS. Yay! my first post!
