76 -90 MHZ ist Standard fuer Japan fuer UKW.
Bei der E32 Serie wurden alle E32 nach Japan ohne Radio ausgeliefert, in Japan wurden dann Sony eingebaut in Japanausfuehrung, diese lassen sich nicht umstellen auf EURO Frequenzen.
Dann habe ich einen E36 M3 aus 02.1998 aus USA, der tat es auch nicht hier in Japan. Wieder andere Frequenzen.
Hier was dazu:
Second-hand automobiles imported from Japan contain a radio designed for the Japanese FM band, and importers often fit a "converter" to down-convert the 87.5 to 107.9 MHz band to the frequencies that the radio can accept. In addition to showing an incorrect frequency, there are two other disadvantages that can result in undesired performance; the converter cannot downconvert in full the regular international FM band (up to 20.5 MHz wide) to the only 14 MHz-wide Japanese band (unless the converter incorporates two user-switchable downconvert modes), and the car's antenna may perform poorly on the higher FM band. Also, RDS is not used in Japan, whereas most modern car radios available in Europe have this system. Also the converter may not allow pass-through of the MW band, which is used for AM broadcasting. A better solution is to replace the radio and antenna with ones designed for the country where the car will be used.
Australia had a similar situation with Australian TV channels 3, 4 and 5 that are between 88 and 108 MHz, and was intending to follow Japan, but in the end opted for the western bandplan, due to CCIR radios that entered the country. There were some radios sold in Australia for 76 to 90 MHz.[7]
