Does anyone know if we can do software updates on our HU without going through a dealership? Since I upgraded my cell phone to an Apple 13, my phone will not connect to the HU automatically. Also, here in the US, all cell companies are shutting down the 3G network, which would be part of the software on cars from 2019 and older. So, I am hoping to find a DIY solution and not have to take mine to a dealership.
