Perhaps this is common knowledge but I thought I would post here in case it is unknown to others
I recently read that Cortana can be activated over in-car bluetooth by dialing (555) 555-9876. I added that number to my Tundra and it worked. a Little clunky “Dial by name”, “Cortana”, but much safer than fumbling with the phone.
I have wanted something like this for a long time – only accidently stumbled across it while reading other articles. Nice feature
