I have a 2020 2500 Denali. Spent a crap ton of money on a new speaker system because I wasn’t happy with the stock one. All the sound comes from the 2 tiny dash speakers. Bose did a terrible job. Now I have this NAV Tv unit to process the signal and it is horrible. It cuts off or gets static depending on how it’s feeling. They have no solution for the issues. They told me to switch to RCA’s because the TOLINK is having issues. Well this morning I don’t have sound again. We even replaced the amp to make sure. This is complete BS. I would have stuck with the stock stereo had I known this would happen. I now have a 75,000 dollar truck without a stereo. Do not upgrade your new truck until some other company comes out with a signal processor.
