Same issue in my LX, still no fix?
I think I found a workaround to avoid the bluetooth from glitching. If you disable the wi-fi on the iPhone, it seems like the glitching goes away (or at least gets greatly reduced). You have to completely turn-off the wi-fi (settings/wi-fi -> off). Let me know or like this if this worked for you.
Mine is having the same issue.I’m not sure I will have to take a look at it tomorrow I haven’t paid much attention to it. I know if I hit the button on the steering wheel and say the name of the contact person it seems to work OK . Have you checked to see if there are any updates for it?
