Trailblaizer Rear Park Assist

[MarauderPadfootGY161]

Hi! I got a 23tb Rs AWD in December. They sent the steering wheel heater but not the rear park assist yet. How does it work when they get it? I called GM but they don't know. Thanks!

from what i know the sensor in the back bumper activates when u r in reverse. if u get too close to something it will beep and let me tell u, its loud!
