Drive a 2006 or newer vehicle? If equipped with OnStar 3G (no Wi-Fi®) or 4G LTE (with Wi-Fi®) system, your vehicle may qualify for a 3 Months On Us trial*15 of the OnStar Guidance Plan (excluding Hands-Free Calling minutes), which includes a comprehensive suite of OnStar services. 4G LTE equipped vehicles also receive a 3 GB or 3-month data plan trial, whichever comes first. Here are some of the available services (available services vary by vehicle):

  • OnStar Emergency Services: Never worry while on the road. Also includes Automatic Crash Response.*2
  • Stolen Vehicle Assistance*4: To help quickly recover your vehicle should it be stolen.
  • Turn-by-Turn Navigation*6: To guide you every step of the way with easy-to-follow voice commands.
  • Advanced Diagnostics*10: To keep you in the loop on some of your vehicle's needs. OnStar can run a check on some of your vehicle's key systems. Enroll in the following notifications and remain on top of your vehicle’s health:
    • Diagnostics Report: OnStar will send you a monthly Diagnostics Report email, letting you know if maintenance is needed on those systems.
    • Diagnostic Alerts and Proactive Alerts: You can be notified of your vehicle's health in real time by email or text, based on your communication preference.
    • Dealer Maintenance Notification: Your vehicle will send a Diagnostics Report to your preferred Dealer who can contact you to schedule service.
  • Remote Access*12: Remotely start your vehicle, lock and unlock the doors and activate the horn and lights, all from your vehicle’s mobile app.*13

After your trial period ends, you can stay connected with the OnStar Basic Plan,*1 or choose a paid service plan, or hand pick add-on services that are right for you.

Simply start the process here — all you'll need is your Vehicle Identification Number (VIN). Once you have confirmed that your vehicle is eligible, push your blue OnStar button and ask the advisor to activate your 3 Months On Us trial.

Enjoy the services you're entitled to by turning on OnStar. There is no commitment and no obligation to provide payment at any time.
