W140 - Japan screen language

u can't even use the radio since the FM Frequency in Japan is different from the rest of the world. so, i just installed a new, additional, Sony CD, radio receiver unit with remote control and installed under the steering wheel a bit to the side. it even has IPod control. radio is clear and sound is great. was difficult to find a guy who can actually do this job, but finally i found one.
good luck.
