I just bought a 2019 ram 1500 with the Harmon kardon system in it. And to me doesn’t sound like it’s performing at its full potential and is lacking in bass. I looked at the version it was on and it says 12.1 after SBX in the application version. I was looking through forums and saw that people were on like 39.9 and 40.1. Is there a way I can update it myself or do I need a dealership to do it? Also, I looked on the website to check for updates and it said none are available.
