The frequency issue was never resolved. However, i have met a ecu specialist who fixes these issues. he recently converted an x5 to receive all european frequencies. I'll continue to wok with him and see what we can do.
I'm surprised we have not yet found anyone in germany with allt he US military - there should be dealers who are converting these cars and servicing them?
BMW insists that the new radios/nav on US-spec cars no longer convert to EU-freqs or receive RTTI. So much so that they ended up giving me back the cost of the navigation and BMW assist--BMW AG in Munich told me before I bought the car that all would work fine. Someone recently suggested to me that it may be necessary to get the navigation maps updated (mine came from the factory with a "Testmap" version. It is on my list of things to do. It is too bad that RTTI doesn't work here in France esp because the road network is really well wired up for traffic info.
If your contact does manage to get something worked out with a E9X, please share as there are a number of folks interested in this little problem.
