I'm new here and this would be my very first post! I just got a 2021 Corolla with the upgraded multimedia and nav system, but its not working right, Miracast and MirrorLink don't connect, the navigation struggles with addresse. I reported it to the dealer, they promised a fix last July 21st, but now they're not responding. I'm thinking of reporting it to the authorities, but in the meantime, has anyone found a way to get this system working properly??
