Finally got around to taking my ZR2 to my local Chevy dealer to have it updated to the ZR2 startup graphics, and was hoping for the new sport mode. When I dropped her off I was already told the sport mode wouldn’t be an option . 2 hours later they call me and say they can’t do the graphics/update or anything…. Is there any truth to this, anyone else encounter this issue?? If not, thinking I’ll try the next closest Chevy dealer when I have the time.
