Hi, I was hoping someone on here could help me. I recently decided to do the sourceforge mylink unlock which upgraded my software. I also got a Nav-Tv GM-K PRG kit for a back up camera. Turns out the Nav-Tv won’t work with the updated software and would love to go back to my old software. My old software was 20.00-94552572. I have a 2015 Chevy Spark. Any help would be great!
