Unfortunately the author of the 'USE A TCU INSTEAD OF A ULF IN ANY IBUS CAR!!!111' thread has neglected to add this to his first post even after I PM'd him about it.

big bob, if you are referring to this thread, I do not recall ever receiving a PM from you or anyone else about international market cars.

That said, I probably would not change the post because it is written at a level above international market coding. The point of the thread and the ensuing posts is that it was previously believed that only the ULF could be retrofitted into an early model year I-Bus car. We learned that it is possible to retrofit a TCU as well.
I do not have first-hand experience with all of the international coding and wiring options. I do know from several phone and email conversations with Martin of BimmerNav (the guy who pretty much figured all this Bluetooth retrofit stuff out), that TCUs and ULFs can be plug-and-play retrofitted into most non-U.S. market cars as well. Some international market cars are not pre-wired, and some the pre-wiring is unique to the phone type. But even those are retrofitable without dealer coding.
Judging from the number of people all over the world who have used this post and another one like it, I do not think that anyone is getting bad advice. To the contrary, they have expressed great gratitude that the BMW community has figured this out together and made the information available.
