I've searched, and read most of the threads, and thus far been unable to really find an answer.
Earlier this week I swapped a 2010 VCIM out of a Yukon (part # 20829984) into my '08 Yukon Denali. Swap went well, no problems pairing my phone via Bluetooth, all that works.
My understanding is starting in '09 is when Bluetooth was added, then starting in '10 is when the RemoteLink app functionality was added, and then from '11+ the connectors changed on the boxes and an adapter is required if retro-fitting.
If I understand correctly, on the mirror I should now have a red light instead of a green light since the info (VIN) in the swapped VCIM doesn't match the vehicle VIN correct?
My mirror light is still green after several days, key cycles, etc.
As for activating an OnStar account. I've never previously had OnStar. If I understand correctly, to activate it, I need to call from the vehicle by hitting the OnStar button, that way when they pull up the module they'll see it as a 2010 Yukon (or whatever the donor vehicle is/was). Per other's experiences, I need to make sure I don't mention anything about what the vehicle really is, that I swapped VCIM's, etc.
Now, the problem is I can't seem to connect to an OnStar assistant. I've tried 4-5 times since putting the 2010 VCIM in, from different areas. When I hit the OnStar button, it says "Connecting to OnStar" audibly, and in the DIC on the dash. I get an audible tone every few seconds (like it's "ringing"), but nothing after that. Nobody ever answers no matter how long I wait.
With the swapped VCIM, the only way to activate it is this way correct? Since if I try to do it over a regular phone, or online, there's no way to have it link to or recognize the transplanted VCIM unless I'm missing something.
I did stumble upon a thread over on a CTS Cadillac forum where someone had posted about the OnStar in their pre-owned vehicle not connecting and an individual claiming to be a tech at a dealer stated that if the VCIM had had the OnStar "disabled" that it would need to be taken in to the dealer to have it "reset" and a temporary number assigned to it so that the OnStar service could then connect to it. Not sure if any of that is accurate or valid, just throwing it out there.
I mostly did the upgrade for the Bluetooth functionality, so it isn't the end of the world if I can't get the OnStar working. I did want to get the three month trial though, and give the RemoteLink app a try since being able to remote start out of keyfob range could prove to be handy.
Thanks in advance for any insight, assistance, or information.
