Nothing to worry about with this error, it simply means that it can't pick signs from the Nav, can you check the value of traffic_sign_recognition_0x21_msg_bus is Fusion and if you still get the error change it to road sign detection.HI T_V
"The OBD11 apps are pants, most of the time not working properly as they haven't been thoroughly tested, they are submissions from end users.", thanks Noted. The sports Dial one worked everything else I have manually input with your summary.
"However, if you have activated Car_Function_List_BAP_Gen2 and have succesfully done the Long Coding in CUs A5 and 17 then during the next drive you should start seeing the Traffic Signs in your dash."
I actually did that and got an error on the dash, got a fright reversed it back to stock.. it said "Dynamic Road signs unavailable " or something(cant remember exactly, I can take a screenshot. So should I just drive off and it will start working when the error appears once? Does the car need to sync with the camera?
