Maps Voice Controls are not working when connected to my car's blue tooth
I just bought a 2013 Hyundai Tuscon and the Maps Voice Controls are not working when connected to my car's blue tooth and plugged into the cigarette lighter socket with the lightning cable. When NOT connected to blue tooth, Voice Controls work. Volume is up on the car's media centre and iPhone. I tried another maps app and it's the same thing, so the problem must be with the iPhone.
How can I get Voice Controls to work on my Tuscon?
I am running iOS 26.1 on my iPhone SE 2020 version.
