The radio screen was blank. Found codes in the human module and radio module for lost most network. Used gm tool kit to test modules. Did not have communication with either radio or human. Replaced both with (gm rebuilt) and did all the set up and programing per si. I now have the my link and noise when door opened. When start car is says calibrate device….. I’m not sure what device to calibrate.
Very frustrating. Any help please.
