2020 Plug in no voice recognition in CarPlay

Check to see if you've got the latest software/codec installed on that infotainment system. They're buggy as heck, that's why I use my phone instead. I'm not going to pay an arm and a leg for that convenience - it's just a convenience and doesn't interfere with the operations of the car that gets me from point A to point B. IMHO..

Good Luck...

PS; your in the wrong forum; a 2020 is a gen4 and requires the phone to be attached to the USB port, next to the lighter.

 

i am a 5th gen prime and i have this issue frequently. 'hey siri' won't work. pressing and holding the home button on the carplay screen will force invoke siri, but it won't register anything i say.

holding the volume/power button to restart the head unit will temporarily fix the issue, until it happens again a day or two later. so its definitely on the car end, and its frequent enough to basically make voice commands impossible to rely on (and creates a needless distraction when driving).

i also notice the "hey toyota" functionality is also pretty terrible. saying "turn on the fm radio" takes probably 10s or more while it "thinks" and then its a coin toss if it'll actually work or just silently dismiss itself. i don't really use that feature anyway, but it just seems indicative of how badly they seem to design their software, whether it be first party or 3rd party integration.
