Condition
Some customers may ask why their radio does not respond to voice recognition
commands.
Some customers may also advise that the push to talk button on the steering wheel only
redials the last number called if the telephone is Bluetooth connected to the vehicle.
Cause If the vehicle is equipped with RPO IOA or IOB, the radio is not equipped with embedded/
native voice recognition.
Correction
As outlined in the owner manual, voice pass-thru must be used to access voice
recognition commands on a connected, compatible cell phone.
As a result, a phone with applications such as Android Auto (compatible Android
Phones), Apple CarPlay (compatible Apple Phones), Siri, or Voice Command must be
connected to the vehicle in order to access voice recognition commands. Please refer to
Chevrolet/GMC Owner Center for more information.
Also review your cell phone manufacturer’s user guide to determine if it supports the use
of these phone applications.
Parts Information
No parts are needed for this concern.
