Finally got Techstream operating on my laptop this morning. I went and plugged it in and connected to the vehicle. I've played around with it for the last hour but cannot seem to find anything that can be customized so... is there anything customizable on a 1999? Techstream believes that my LC is a 1998 but the VIN says otherwise. Regardless of what system I go to, when I click Customize nothing populates. Any ideas?
