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.
Recently there was a Technical Service Bulletin (TSB: 23-016-21 REV. A ) that appears to address concerns similar to the symptoms that you are having with your vehicle. To ensure this TSB applies, we would like to get you back into the dealer to have a qualified technician review the details of the TSB and specifics of your vehicle.
