2016 Yukon - Replaced GPS Antenna AND HMI - NAV Still not working

I have the same issue. Can you give me the part number for the On Star module? And technical name? I"m not coming up with anything under On Star module.

The dealer replaced the onstage module before I got the truck so don’t have the part number. Could probably call in to get the exact part?

You might want to provide a few details about your rig: year, make, model, trim, engine, etc. Consider adding it to you signature so it's always there. That way others who post responses can provide pertinent info.
