2024 on lockdown
You only need an Onstar sub if you do not have a phone capable of Android Auto or CarPlay.
Install and enable Android Auto on your phone. Then on the car, pair the phone using bluetooth and allow permissions when the link is created. Launch Android Auto from the infotainment main screen and set up the options and settings for automatic start up and login.
Now every time I get in my car and start up, the system boots up and links to my phone and displays the navigation and media windows and starts playback of the last track.
This uses your phone's data connection, not the cars so no Onstar ransom is needed.
CarPlay setup is similar but an Apple device user would have to assist with any particulars.

Some of them, like Here WeGo, MapFactor Navigator, Maps Me, and the rest can be used to download map files for offline use. No subscription (angst) required.
So, if the subscription thing is a problem for you, park your car at home, connect your car's network to your home wifi router (think it's in the Settings/Network menu on the DIC), get one of these apps off the Google Play Store (some or all are supposed to be free), install it, do the offline maps download (some have built in notification when newer maps are available for download), and use it like a built in GPS navigation system, which is what they do.
I've used MapFactor before and it's not bad.
If Waze has an "offline maps" capability, use it, and you're good to go.
Be resilient, be creative, learn new skills, it's all good.

Car isn't handy or accessible due to weather, so I can't verify that.
Haven't driven it in over a month, but when I get back into it, I'll try it, and post up results, if I remember.
I think someone was unable to get their My Chevrolet/My GM app to synchronize with the car's status data (tire pressure/fuel level/oil life), until they called OnStar, and voila.
I’m sure this isn’t news but when I am going somewhere new I usually look up where I want to go on my iPhone while sitting on the couch. Usually using Google. The restaurant/museum whatever shows up in my Google search. Below is a “directions” icon. Click the icon Google maps puts a map on my phone screen with a suggested path. I get in the car. Plug in the phone and hit “start direction” or whatever it says and your phone Nav function becomes your car Nav function. I’m sure there are more apps and more methods but that’s easiest for me.

Made up a gmail "handle" and created a basic email address when I retired in 2004.
I've never spent a penny on anything Google or Android (except some pricey phones).
It's actually pretty easy. Let's assume you can get your car's network connected to your home wifi router when you're sitting in your garage or driveway.
You use your (free email) google account to sign in to the C8's Infotainment system, access one of the offline map nav apps on the Google Play Store.
Down/up load it to the car, and install it.
Open the app, and download the maps (US/Canada/North America) to the car's hard drive (as I said before, I believe the on board SSD capacity can accommodate this).
Fire up the app, and try some simple directions from point A to B to test it.
It's not rocket science.
If it's a task that's beyond your level of GM/Chevrolet "tolerance", then I can't be of more assistance.
Sorry. Best I can do.

is this something you have actually done? (downloaded something from the Google store to the C8 and use it to navigate from A to B)

It is my understanding that the car comes with GPS built in, like most phones and other Android devices, so that part is included.
The apps mentioned in the prior post are all capable of using "offline maps" that can be downloaded to the car's Infotainment Android System, so that needs to be done for them to work "offline", as in, when there is no cell service available.
Just like a standalone Garmin GPS unit that we used to use (I still have 2 of them that work fine with Lifetime Maps subscription, included in their price).
Maps and GPS capability are all you need using this method. But you need to install the app, and download the maps first.
No OnStar subscription required.

This would be very helpful. I don’t generally connect my phone to my car so it would be great to have Nav in the car without the blood sucking Onstar subscription.
Any other 2024 owners running a Nav app in their C8 without the Subscription?
I’m amazed (and thrilled) that this work around is available. I would have thought for sure gm would block the cars gps from being used by a non subscription app. This is a game changer if I can add my own Nav and have it work with the infotainment screen.
