Can I access my account from the app?

Yes, you can view your account information, check your plan details, and speak with an Advisor directly from the app.

Can I use Turn-by-Turn Navigation with my vehicle’s mobile app?

Yes. You must have the Guidance Plan, your vehicle's mobile app and an eligible vehicle to use the location search and send functionality.

Can I send a destination to my vehicle from the app?

Yes. Select a location from your contact list, or search for a point of interest. You can then send the directions to your selected location directly to your vehicle's OnStar Turn-by-Turn Navigation system.

What other features do I have in my vehicle’s mobile app?

You can remotely start and locate your vehicle, view Advanced Diagnostics, lock/unlock your doors, sound the horn. Learn more here.

I drive an electric vehicle. Do I have any special features in the app?

Yes. In addition to the standard capabilities of your vehicle's mobile app, drivers will be able to easily manage the capabilities of their electric vehicle with extended range including setting charge alerts, checking on current battery charge level and contacting a dedicated Advisor. This includes:

  • Remote commands: Your vehicle's mobile app will allow you to control a number of key vehicle functions and OnStar features from your mobile device. Drivers will be able to manage vehicle charging, read the state of battery charge, and review vehicle history data such as odometer readings, miles per gallon and miles driven in EV mode. In addition, you can perform traditional OnStar and key fob functionality such as door lock/unlock, horn and lights.
  • Charge command status: You will receive a message on the application when a command has been successfully sent to the vehicle. If in view of the vehicle, the dash LED will be solid when charging, flash when the charge is on delay, and blink quickly if the battery is full and the vehicle is still plugged in.
  • Smart grid: Your vehicle's mobile app allows you to manually select "grid friendly" mode. This allows you to select the time of day when you want your vehicle fully charged. Under typical circumstances, this would allow the vehicle to be charged at off-peak times and reduce the impact on the grid.
