The 2017 Bolt has the mysterious K56 module already. I wouldn't get too excited though. The salesman explains that GM under Mary Barra is ultraconservative when it comes to safety (liability), anything related to changing the car part of the car is going to be done by service where there is ironclad documentation of what, who, and when. The fluff part (infotainment), that's already being OTA'd.Based on some recent posts, it looks like the 2018 Bolt will have an OTA update module. Assuming that's true, what it may be used for is unknown.
