GM MyLink Programming (with module)
1. Begin by connecting the provided GM IO-PRG Module to the OBD2 Harness via the 18-pin connector.
2. With the key OFF, connect the red OBD2 Programmer connector (with module) to the factory OBD2
port.
a. Watch LED on module before engaging ignition
3. Turn the key to the IGNITION ON position. Watch the LED on the IO-PRG Module and verify flash codes
below.
4. Wait for radio to reboot fully.
5. Cycle the vehicle key once (turn off, wait 5 seconds, turn back to IGNITION ON)
6. Verify 5 FLASHES from LED on module.
7. Disconnect the OBD Harness and module from the OEM OBD2 port. The module must remain in the
vehicle, but do not leave it attached to the OBD port.
8. Verify that the radio accepted the program properly by placing the vehicle in reverse (vehicle may need
to be running). The reverse screen should appear (or black screen/attention text if no camera is
connected yet) when in reverse only.
9. UPDATE: if nothing happens in reverse after
programming, disconnect the 20-pin power
plug (black) at the OEM HMI module, then
reconnect to reset the system manually. Once
the radio has reset and booted fully, test for
rear camera activation again.
NOTE: There is NO De-Programming option with either GM IO-PRG kit. Once programmed, this system
modification will remain forever.
