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 mobile app?

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

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

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

Yes. In addition to the standard capabilities of your vehicle mobile app, drivers will be able to easily manage the capabilities of their electric vehicle including electric vehicle route planning and locating charging stations. This also includes:

 

  • Remote commands: Your vehicle 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. 
  • Public Charging: Use your vehicle mobile app to find, start and pay for charging at public charging stations. GM EVs have access to a growing network of public charging stations that now include Tesla Superchargers (GM-approved NACS DC adapter required). Activate public charging within the vehicle mobile app and order a NACS DC adapter to enjoy expanded access to fast charging throughout the US and Canada.
