Thanks, very good to know. My module should be coming in on Thursday, so I'll be getting the mic, bracket, and antenna locally (maranello bmw). I will try to add $664 to the VO in the modules you mentioned, hopefully I don't end up with a dead bimmer.
I also ordered my TCU form eBay, I'll check getbmwparts.com like yourself and see how different the pricing is.
Also driving an 06 325i (sedan though) prewired for option S664 according to the build sheet. No SOS.
