Buying a TCU for Bluetooth only is not cost-efective, although if you are looking for the best Bluetooth connectivity with compatible phones that's the one to have as it is the official factory supported solution: see how quickly BMW supported the iPhone in the current TCUs, but it has to issue a complete new version (generation) of the ULF module because past versions have issues with that phone. The ULF in the USA has been the "black sheep" in support and compatibility from the factory...
So, a new ULF from Bimmernav might not even be compatible with Iphone? That would be a disappointment.
