Just bought a 2021 equinox after owning a 2016 equinox for 5 yrs and very happy with it. The voice recognition button does not respond like it did in the 2016 .In the 2016 I would be able to change stations on my radio. I would also be able to say a call, for instance " call Fred" and it would respond with " call Fred" and I could answer yes or no. When I push the button on my 2021 i don"t get any response. I cannot change the radio station either. I have had it to the dealer and they cannot get it to work. Is there a phone # for gm that I can call and get this issue resolved. Thanks
