Today I’m going to walk you through what all is in GM’s new software / firmware update, number 663.20, which was recently rolled out for GMC Canyon and Chevy Colorado pickup trucks. There’s some big quality of life improvements here, and we’ll even test one out!

  2. Thanks for letting me know – there are 2 updates that came out one or two days after the other. I still haven’t gotten a notice of 663.30 being available for my truck, not sure why.
