Radio broadcasting have differences between USA and Europe. Because of that some radios bought form USA do not work well in Europe and in the other way. This document tries to clear out what are those differences.
North American FM broadcast channels are on the odd 200KHz frequencies
MHz, etc. In Europe, channels can be on any multiple of 100KHz, even or odd
This means that a digital tuner from the USA will not tune European stations properly, resulting in distortion
. Some tuner models are switchable between the two schemes, but these are rare. Frequency synthesizing tuners in Europe do their actual tuning in shorter steps (for example 25 kHz). With analogue tuners you have no such problem because they aren't stepped anyway.
Be aware that FM stations in Europe use a different pre-emphasis than those in North America, 75 and 50 microseconds respectively.
Same for AM, the difference is 10 kHz steps in the US vs. 9 kHz steps in Europe.
what year is/were your car when is was recoded? I was told by the mechanic at the dealership it is not possible with the e93.
Sorry if I wasn't clear - I was just speculating. Never had it done. It seems like it should be possible, though. If not you would need a euro-spec CCC and have that recoded to the car.
