Hello everyone,

I am working on restoring the hidden Navigation icon on my factory infotainment system. All physical hardware, including the remote SD card reader module and wiring harnesses, are 100% intact and undamaged, but the system is currently hiding the Nav interface shortcut.

I am using an offline GM DPS setup paired with a VXDIAG VCX Nano (J2534 Pass-Thru).

Can anyone provide or help me modify a calibration configuration file (.vbf) to force-toggle the Navigation Option Available parameter bit flag from False to True?

My Hardware Details (from sticker):

• Device: HARMAN INFO3 CSM MY 18 MID

• GM Part Number: 39219085

• Software Version (SW): 150419

• Hardware Version (HW): 070417

• Architecture: GM Global-A / E2XX

I am looking for the specific configuration script/calibration dataset matching this unit tier to avoid security signature violations or boot loops. Any guidance or file shares would be greatly appreciated! Thank you.

Hello, before we get further on this, can you confirm your hardware have the GPS plug for the antenna?
