Vehicle software updates
With vehicle software updates, you can receive free enhancements, purchase new upgrades and get software refinements using over-the-air technology. Updates are downloaded and installed via Connected Access
About vehicle software updates
Using over-the-air technology, vehicle software updates are automatically downloaded to your vehicle. Follow the prompts on-screen to install.
- Make sure your vehicle has connectivity. Avoid parking in an underground garage or covered space.
- To be eligible for vehicle software updates, including automatic Super Cruise®
* map updates (if equipped), you must have accepted the connected vehicle User Terms for Connected Vehicle Services and OnStar Privacy Statement for the vehicle. If this isn’t accomplished at vehicle delivery, you can accept these terms on a call with an OnStar Advisor.
- Update notifications will be sent to your vehicle, and you can also manually check for them using the center display.
- There are two steps to getting the update: software download and installation.
Here’s how to check for updates in your center display or see if your vehicle supports updates (steps below may vary by vehicle). Go to:
- Settings > Updates > Updates and History to check for updates.
- Settings > System > Vehicle Software
- Settings > Software Information > System Update.
Note: If you declined the applicable terms, the vehicle will not be eligible for vehicle software updates. Also, if the conditions for the update aren’t ideal (for instance, your battery state of charge is too low), the update notification might not be visible. In this case, the system will try again at a later time.

Software download
Software downloads are initiated automatically and occur in the background.
- You can continue to use your vehicle normally during a software download.
- Downloads automatically pause and resume if you turn off your vehicle or lose connectivity (e.g., if you pull into a parking garage).
- Download times will vary, depending on the size of an update and your wireless signal strength.
Installation
- Once a software download is complete, you’ll be prompted to accept the installation of the downloaded software update upon your next drive cycle or the next time your vehicle is placed into PARK after a drive cycle. You can also choose to be reminded later, schedule or decline the installation.
- If you decline an update, the update will cancel, and you may need to take your vehicle to a Dealer if you want to perform the update later.
- If you decline an update, the update will cancel, and you may need to take your vehicle to a Dealer if you want to perform the update later.
- You’ll be asked to put your vehicle in PARK and turn off the engine/vehicle to initiate most updates.
- While an update is being performed, you can’t drive your vehicle and the center display may remain active during the update. Park in a safe and secure location before beginning any update.
- Generally, software installation takes about 20 minutes or less.
- You don’t have to stay in your vehicle during an update.
- If you leave your vehicle during an update, close your windows and lock your doors. Don’t leave your keys in the vehicle or lock occupants inside.
