Adding MyLink and OnStar 4G LTE to a 2009 Impala

There are a couple videos on YouTube showing an infotainment system from a 2013-2017 Lambda car(Traverse/Acadia/Enclave) working in an 8th gen Impala. My plan is to take this one step further. I've purchased a navigation radio from a 2017 Traverse Premier, as well as the OnStar module.

From what I have gathered, the OnStar module from the Traverse is electrically identical to the existing one in my Impala. With the Traverse's OnStar module, I can get mobile hotspot capability in my Impala, as well as other features rolled into OnStar Generation 10.

Another added benefit is that those with older vehicles who use OnStar won't be left in the dark when Verizon inevitably shuts down their CDMA network.

Once I receive all the parts, I will post pictures here.

Who said you had to buy a new car to get new car features?

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.

Here's some pictures of the MyLink Radio with Navigation. The radio is plug and play, but you will need a Tech 2 with firmware version 30.004 or older to disarm the stupid TheftLock. Unlike the older Denso/Delphi navigation systems that you would find in GMT900 trucks, this radio does not require a dedicated VSS signal, as it reads the vehicle speed from GMLAN.

There is one caveat, there is a gap between the radio bezel and the radio itself. If the gap bothers you, you can get a MyLink radio from a 2017+ Chevrolet Express van, as the radio faceplate will fit into the opening.
