I posted this on the Technical forum, too, but I'm not sure if that gets as much activity.
Now that OnStar is standard on GM (I'm looking at Hummer H3), I'm trying to find a definitive answer to this question:
Can I completely disconnect and remove the OnStar box? If I do, will it disrupt the engine or other electronics systems? Will I loose anything that is not OnStar?
I know that I can disconnect antenna, remove fuse, pull cord from mirror, etc. But can I pull the box completely?
