I just watched this video of the Lightning software and it appears to have some new games. I assume these will be coming to all Sync 4 vehicles via an OTA update. In the video he plays the “Lane Change“ game. He also claims the software is quicker than previous versions.
I was bored today so I created a version history for the Sync 4/4a Power-Up software updates. I did some google searches to compile the information. I couldn't find very much information and some of what I did find may be incorrect. Feel free to edit the page as you see fit...
