Installed used telematics control module on my refreshed 2022 silverado
You're a genius! I have a 2022 Suburban but my app now shows a 2023 Silverado. Haha! Interestingly enough, I was able to activate OnStar and “marry” it with my Suburban but after driving down the road I got the dreaded check engine light. I removed the entire used telematics module, removed its antenna portion (purple and brown), and placed the antenna portion back into the original telematics module, and placed it all that back in and now no check engine light. We put over 2500 miles on it and no issues at all. Thank you so much for this hack!!!!
Granted the WiFi works flawlessly, I am curious whether or not this affects OTA updates since it thinks its a different vehicle.
