I'm pretty certain that's the case, but I don't really know having not dealt with a BT-integrated headunit myself. It'd also make sense if the mic were integrated into the HU, but I don't think that's the case.
There are a few other people who've done a 'new headunit' retrofit, but theyre a bit sparse. Dig through search and you can probably find someone to PM who mentions having done it.
