I had exactly same problem at 10 months on my 2016 Colorado, Dealership tried reprogramming for 2 days, GM blamed my phone then my thumb drive, then admitted that it was a software anomaly that had no permanent fix. You could temporarily delete pairing and go to original settings and it would work for only a day or two. After a couple month's the HMI module died ,no camera no radio, nothing. Dealership replaced module 3 months ago , everything fine now. Get yours repaired before Warranty expires.
