Software update postponed?

[AlanK]

My '23 Silverado has been nagging me for few weeks to do a software update.  Several times I have given permission to proceed.  But the update has always stopped with a "postponed" message.

 

Where I park, cell service is very poor.  Verizon is 0-1 bar at best.  GM uses some type of "Over The Air" service for the updates.  Is this a cell phone like connection that uses existing cell networks (Verizon, ATT, etc.)?  Does OnStar use the same carrier service?

 

Just wondering what the truck needs to do the update?

 

Has anyone linked their truck to say a mesh network to get better access to service updates?

Onstar uses the AT&T network.

Your truck can connect to a wi-fi network.  You can connect your truck to your home wi-fi or connect it to your cell phone hotspot, if you cell phone has a good signal.

OK.  Thanks. I went to town and my truck was able to download and do the install.  I think it just needed better cell service and 15 minutes of "off" time.
