BM53 works in European frequencies i.e. ECE, just like the other radios..

I have a BM53 equipped car in Europe, It was in USA mode and I was not able to get about 1/2 of the available radio stations, when I switched it over to the ECE/Europe mode, everything came in.

The BM54 SHOULD have this function, just about every BMW made has this function for the exception of the NEW X5 and E60 with CCC.

I would like to know for sure that the BM54 can do it and if so, can it support Sirius (I doubt)
