Well I have given up n upgrading my On star box. The one I purchased out of a 2009 Sierra Denali didn't work. I took the truck to the dealer to do a complete re flash and still no bluetooth. It seems that the voice command to pair with the bluetooth is not in the system. So now I have a perfectly good On-star box w/bluetooth for sale $75.00 OBO If anybody is interested contact me here
So i found a vcim out of a 2009 Sierra. Installed it but still no bluetooth. It does not recognize the "bluetooth" or "pairing" command. I was able to reach the on-star tech..but no help. So I took it my local GMC dealer to have it flashed to recoqnize the VIN. Dealer was unable to flash it as it came back as unrecognizable. Anyone have any idea what I am doing wrong??
Hi guys, I am a new member. I have a 2008 GMC Sierra Denali. that I am trying to swap out my old On-star box for a newer model with bluetooth. I purchased a 2014 sierra box on ebay. I plugged in no problem. However I cannot get a pairing. The voice command say it noes not recognize the command "bluetooth". So I tried initiating a call to On-star..but I get action for pressing the on=star button. I also noticed that the voice command works without the on-star box plugged in. Does the radio need to be flashed for this?? Any help would greatly appreciated.
