Radio Upgrade 2017 Tundra SR

My standard tundra radio just stopped receiving AM stations completely and only gets strong FM stations. I was lucky to find someone giving away their 2017 HD XM tundra radio from his TRD. I installed with no problem realizing I wouldn’t have all the features available but for the life of me, I can’t figure out how to set the clock. It’s currently selected to get the time from GPS, but that function is grayed out. Is it possible to change the clock from GPS setting to manual. Any help would be appreciated. PS: I don’t have steering wheel controls.

 

See if this helps. Looks like you can toggle the auto adjust by GPS on and off

Thanks but no joy there. The settings to adjust AM or PM, or turn off the gps feature are grayed out. Pic attached.
