The vendor I purchased my 2005 Tahoe from appears to not need any future business from me, as they will not return calls or make guaranteed fixes after the deal. One issue I'm having is with Onstar. The 2005 framework has all the earmarks of being both simple just as advanced. I have been told by the seller that they set up the membership, that all I would need to do is press the blue catch. I've done it and hear only a signal several seconds. I calculated that they were blowing smoke my direction, so I went to the Onstar site and actuated the membership (3 months free of charge) and was sent bearings that said to press the blue catch. I did, with a similar outcome. I'm getting exceptionally baffled with this, and am going to tear the framework out and introduce a module which would permit me to utilize bluetooth connect with my telephone through the truck's speaker system...but I'd lose the capacity to follow my truck on the off chance that it were taken. Anybody ready to assist me with this?? 192.168.100.1 192.168.1
