Question about 2011 GMC Terrain
I have had these same issues with my 2011 Terrain. I just read on the equinoxforum.net that there is a softwear update/upgrade (# PIO285) available. It is supposed to fix these problems. It is recommended that you take your vehicle to a GM dealer with this information. I am taking mine next week. Good Luck!

SOURCE: Hello, I just purchased a
there is supposed to be a power constant connected to the stereo, which would allow power to continue while the car is not on. you could have a blown fuse, or the radio may not have been installed properly. the power constant lead is usually a yellow or blue wire (one or the other, i cant remember which, off the top of my head) coming out of the rear of the radio/harness, and should be connected a fuse which always gets power (usually labeled as "acc constant"), or should be connected directly to the battery.
