I took my Wrangler JL Sport in for service. I bought the Mopar LED kit and installed it, and wanted to take it in to get the system flashed to get them fully functional. Also had the electronic stability control message come up and I had some larger tires put on so I wanted them to adjust the speedometer. I wanted those three items resolved. Left the dealership with over a 1100.00 bill and only the headlights working the told me the speakers I had installed are causing the error codes(had the speakers installed by a reputable shop) and the electronic stability control message to come up. The stability control message came up prior to the install of the speakers. Am I crazy any advice on how to proceed? This is my first Jeep and it is by far my favorite vehicle I had ever owned. Any advice would be greatly appreciated. I have attached some pictures the dealership sent me.
