Purchased a 2019 Bighorn in July 2022 with 24K miles on it, immediately noticed that the nav volume is unbearably loud, it’s set to 1 and if I could make it quieter, I would. Same issue with incoming text messages and phone calls. Dealer couldn't figure it out and installed a new radio but still the same issue. Getting desperate for an answer, this is my first Ram, starting to wonder if it was a smart choice.
