Try pressing the button on the steering wheel and say help. It may give you a list of commands. You might want to check your owners manual to see if there is a list in there also. If you don't have an owners manual, you can download it here on the site. Click on Model Center and then 2004 and you will see it come up. Try also looking on OnStars website to see if they have a guide to download.
This is just too cool. I have an 04 and don't know if the onstar was upgraded and I don't have the onstar book could someone tell me what the commands are?
