Upgrade my software from 2.0 to 4.0 so I can use onstar

Our team can understand your desire to have the full range of OnStar services in your 2013 Cadillac SRX. For your awareness, the wireless network providers that support our services transitioned their cellular towers in the U.S. from 2G networks to 4G or 5G connectivity. The transition was completed in December 2022. After this transition, 2G network connectivity is no longer be available. The decision to sunset these networks was made by the wireless network providers and the need to upgrade to newer technology to support our expansive variety of services. To stay connected after the network sunset, we encourage owners with 2G-connected vehicles to download the OnStar Guardian™ app. This handy app allows you to take the most important safety and security OnStar services wherever you may go. To learn more about the Guardian app, we recommend visiting our website at OnStar Guardian App | Safety Services Right on Your Phone.
