sentences:  In addition to showing an incorrect frequency, there are two other disadvantages that can result in undesired performance; the converter cannot down-convert 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 down-convert modes), and the original antenna may perform poorly on the higher FM band.Another problem is that RDS is not used in Japan, whereas most modern car radios available in Europe use this system.Also the converter may not allow pass-through of the MW band (if desired).
