Hi, Latindeer from North Carolina,

I suspect GM's GPS is like their other units: It needs to know where it is before it can get along with its neighbors. After installing a GM unit, it has to be instructed to run the Learn VIN routine, else you'll get the security warnings. Use your OBD-II scanner and go to the GPS Set Up menu and click Learn VIN. If you don't have a scanner, visit your area auto entertainment electronics specialty shop for a set up -- that's most likely where your dealership would send it.
