When I use the voice recognition feature on the iPhone, linked through the Corolla Bluetooth, it doesn't recognize and hardly picks up my voice. It seems to be a volume issue but even if I scream it often doesn't come through and spell out correctly in texts, web searches, note dictations, etc. I've also noticed people are having a harder and harder time hearing me on phone calls. I reset the connection from both ends, reset the audio system, adjusted volume, went through the voice training feature, etc. Does this mean the Bluetooth microphone is going bad? Or is there a setting or compatibility issue? I have an iPhone 8 and the Corolla is a 2014 LE Eco model bought in fall of 2013 - the first one the dealer sold when the redesign was released that year. Any help or advice is appreciated, it is very frustrating...
