The functionality of the GMC mobile application varies, with certain features requiring an active OnStar subscription, while others are accessible without it. Basic vehicle information and remote commands often depend on the presence of a connected OnStar service plan.
An active OnStar subscription facilitates services such as remote start, door lock/unlock, and vehicle diagnostics accessible through the GMC app. These connected services offer enhanced convenience and security, providing users with greater control and insight into their vehicle’s status regardless of location. The historical development of telematics systems like OnStar demonstrates a growing demand for integrated vehicle connectivity and remote access capabilities.
