i sent ur question to a friend of mine who is a Rep for Vizualogic. Here's his reply -

"Well, the systems that fit US model BMWs will fit the seats in the European models. BUT, the built-in RF modulators (only in the new A-1000 & A-2000 series, which have the built in DVD) use US tuning frequencies. In Europe, radios stations end in even numbers (i.e.: 105.6), while the US radio stations end in odd numbers (i.e.: 105.7). The FM modulator broadcasts on low band FM frequencies, such as 88.3, 88.5, 88.7. If you were using the Advantage series of product (without the built in DVD and FM modulator), you could simply use a modulator available in Europe. You could, however, use the new A-1000 and A-2000 series headrests, but would have to use the RCA audio outputs from the Vizualogic kit."

Hope this helps.
