MirrorLink microphone not working please assist..

I have enabled full MirrorLink, however the microphone is not working. When connected it opens a MTP USB connection and disables BT media on my car. I have tested various settings and have been able to get everything to work using bt mono however the audio quality is horrible when playing music. So returned to app and I have used your search shortcut to give me access using bt mono to at least use Ok Google when I click on it but no other apps work with microphone. Is there any other way anyone knows to have the phone use another microphone perhaps one on phone? Or perhaps any way to make these specific apps like Google maps voice search use bt mono?

Full MirrorLink means I have my entire phone displayed on my stereo. Litterally everything is working except microphone. Netflix, streaming from Put.io, YouTube and I have got keyboard working all in motion and no ODB used..
