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?
