I know. The guy said they have tried "a few Fusions" and this converter does not work. I have the single disc CD/MP3 with the AUX button. Still, I know both the 6 disc and single disc stereos are the same ones in other Fords. I mentioned this to him. He said "that is what you would think". He wasn't really able to explain other than it was a "bug". But, he gave me his answer quick. He didn't put me on hold or sound like he had to look the question up on a computer. I assume this has come up already. I still don't get it.
