Have you tried OnStar voice recognition?
For you new folks....
I am a true believer in "hands free" calling while driving. Statistics show that people talking on cell phones have the similar statistics as driving while legally drunk. (And who among us us could doubt that, given the all the weird driving we see on the roads these days.)
I will admit that I do use OnStar for the quickie phone calls that I make while diving. OnStar is more expensive than my cell phone, but the "delta" really is virtually insignificant in the grand scheme of operating the XLR. (No I dont work for them, and this is not a sales pitch) In Texas when talking costs not worth worrying about, we say, "That's like pickin' S*** with the chickens."
OnStar really is like a cell phone. If you havent done it yet, push the white button and at the "OnStar ready" prompt, just say "Dial". The prompt then says "number please", and you speak the number one digit at a time, then say "Dial". Hot OnStar chick then cheerfully says, "Dialing!"
The biggest disadvantage is when you need to dial any additional digits after the phone picks up, like if there is an extension number, or if you are trying to page someone.
I've also learned to store and retrieve "nametags" for frequently dialed numbers. Nametags are simply memorized numbers that use a single voice prompt to recall and dial. I think the technology is convenient and cool, the Bride thinks using OnStar for normal calling is a waste of money. We disagree. I guess that why there's chocolate and vanilla. More OnStar minutes for me...
