It's mostly tracking software to sell you you next vehicle or accessories for your current.
It doesn't look like anything I need then.
Here is how things are shaking out for me. The only apps in the infotainment apps that have any significant value are Android Auto, CarPlay, and MyChevy for searchable access to the owner's manual. The voice recognition of the Nav app is abysmal even if you do get a subscription. It couldn't find major landmarks or chain stores and I only succeeded getting it to recognize a local non-chain doughnut shop. The stuff integrated into the steering controls works well, and MyChevy's value is the owner's manual. The only value I can see with OnStar is the same value it had 2 decades ago before infotainment centers were in cars.
