Update: VCIM Swap Complete!
There is one modification that needs to be done to the Generation 10 module in order for it to be plug and play. There is no programming needed to install a Generation 10 VCIM in these vehicles.
You will need to get a VCIM from a 2016-2017 Traverse, 2016 Acadia, or a 2016-2017 Enclave. Other Gen. 10 VCIMs communicate on GM's "Global A" electrical system and will not communicate with the vehicle.
- For people upgrading from a Gen. 7 or Gen. 8 VCIM(2006-2010), you will need to modify the GPS antenna connector. You will need to bust the "key" off the connector on the OnStar box, or on the GPS antenna itself.
- If you're upgrading from a Generation 9 OnStar Module (2011-2013, 2014-2016 Limited), you will need to get a splitter and cables to connect to your antenna(GM p/n 20960972). I am not sure what the part numbers for the cables are, but I'm sure they can be found online.
Everything works, but there are some side effects.
- Onstar will think your car is whatever the vehicle your VCIM came out of.
- Oil Life will be inaccurate on the RemoteLink app on 2006-2011 vehicles.
- Fuel range might also be inaccurate in the RemoteLink App.
- No Bluetooth handsfree functionality - on the Traverse/Enclave/Acadia, this is handled by the radio, not the VCIM.
Here's a demonstration of the Wi-Fi Hotspot working in the Impala.
