Are you using the command "call" before you say the name?
I am having the exact same problem. The sad thing is it worked for 18 months! They are trying to say its my phone...I'm positive its not as Siri works just fine on my phone. I too want a solution.Hi All! I'm a first time Buick owner & am having trouble with my voice command to call someone in my contact list. If I dial using the phone number I see the contact name on the display and the call goes through. If I say the contact's name the system tries to take me to the navigation command. is anyone experiencing this and do you know a fix? I've only had the car a little over a week...really frustrated. Maybe it's my phone settings but I can't figure out what the issue is.
Thanks for any advice!
