No. You need to buy the navigation update from GM.

Looks like they are on USB memory sticks.

Google GM Navigation Update.

Just a heads up. I did this on my '14 Equinox, you need to leave the car running about 45 min which I did in place in the driveway. However, I went into the house and my neighbor thought we left the car on and shut it off. This messed up the navigation on the car and we couldn't get it to reset right.
