: xm and onstar question

12-12-08, 12:02 PM
I have an 07 escalade with the nav screen etc. Once the vehicle has ran for a bit the xm catagorys dissapear and the onstar phone won't work the numbers on the screen are ghosted out, if I try to use the button on the mirror and say the phone number it dosen't dial. I seem to have the dealer confused with all of this. Thanks for your help.
