I ran the warranty claims on the 2000 Blazer that my wife just got and there were several line related to re-configuring and replacing the IUV - it looks like some place in Texas reprogrammed it. Does anybody know what IUV stands for? I've done some searches and nothing useful comes up. It has to be some sort of computer module. Thanks.

 

onstar module

 

Yep, onstar crap. If yall don't use it I wouldn't pay for it

 

Thanks for the replies. Actually I would use it if I could but I don't think that the anolog OnStar system on the 2000 Blazer is upgradable to digital.
