As usual, they are full of shit. I was having different Uconnect issues. They had my dealer perform that update back in JANUARY. It fixed my problems. But, I still don't have traffic. Never did,Another update.
We have a tbm update that goes in Oct 3rd when we are back from vacation “all 2021 models have issues with connected services but the 22 and new models do not. When this update is applied, your connected services will work”. So here is what you should tell your dealership if you have a 21 model. I have a 21 overland. Don’t know if this should apply to any other trim level.
