GMC Car App — Lock, Unlock, Fuel & Location from Your Phone
CarConnect works with GMC vehicles: lock and unlock from anywhere, see live location and fuel level, and keep documents and service history in one place — all from your phone, with no wiring or extra hardware. It requires an active connected-services account (OnStar (myGMC app)) and a supported model year.
GMC models CarConnect works with
11 GMC models, generally from model year 2010 onward. The free compatibility check names exactly what your model and year supports, in a few seconds, with no account and no card.
Your GMC, in your pocket
Lock & unlock
Lock or unlock from anywhere — no key-fob range limit — and see the real lock state, not a guess.
Live location
See where the car is parked (or headed) on a live map, using the vehicle's built-in GPS.
Fuel & status
Fuel level or EV charge, odometer and vehicle status at a glance before you leave the house.
Documents vault
Insurance, registration and service records in one place, attached to the right car.
Service reminders
Maintenance history and reminders so nothing on the schedule slips.
Feature availability varies by GMC model, year and connected-services plan — the in-app compatibility check shows exactly what your car supports before you subscribe.
Connect your GMC in three steps
Check your GMC
Pick your GMC model and year in the free compatibility check — you'll know in seconds whether your car qualifies.
Activate connected services
Make sure your OnStar (myGMC app) account is active. Most recent GMC vehicles sold in the USA already include one — your dealer can confirm.
Link and go
Sign in to your connected-services account inside CarConnect. No wiring, no hardware — your GMC appears in the app in minutes.
GMC owners ask
Does CarConnect work through OnStar on a GMC?
Yes. GMC's connected services run on OnStar and CarConnect links to that account, then shows lock control, live location, fuel or charge level and odometer.
Can I find the truck in a crowded lot?
Live location comes from the vehicle's own modem, so there is no range limit and nothing to install. It shows on a map wherever it is parked.
Does it work on a Hummer EV or Sierra EV?
Electric GMCs report charge level and range on the status card, and on supported models charging can be started, stopped and limited from the app.
Sierra, Yukon, Acadia, Canyon — covered?
They are in the supported GMC list, generally from model year 2010 onward. The free compatibility check names what your exact model year supports.
Does CarConnect work with GMC vehicles?
Yes — CarConnect works with GMC vehicles that have an active connected-services account (OnStar (myGMC app)). Once your account is linked, you can lock and unlock, check location and status, and manage your car from the CarConnect app.
Which GMC model years are supported?
Coverage generally starts around model year 2010 and depends on the model and region — support comes from the vehicle's built-in connectivity, not from any hardware we add. The fastest way to check is the in-app compatibility check: pick your GMC model and year and you'll get an instant answer.
What do I need before connecting my GMC?
An active OnStar (myGMC app) account. Most GMC vehicles sold in the USA in recent years already include one — your dealer can confirm or activate it. No wiring, dongle or extra hardware is needed.
Does CarConnect replace the official GMC app?
No. CarConnect is an independent companion app that works alongside the manufacturer's own app. Many drivers prefer it for its clean interface, multi-car garage (even across different makes), and extras like a documents vault and service reminders.
What if my GMC isn't supported?
If the compatibility check can't match your model, it's usually an inactive connected-services account or an older model year. Reach out at support@loopmobile.io and we'll check your exact configuration — every plan is covered by a 15-day money-back guarantee, so trying CarConnect is risk-free.
