Due to some ongoing Bluetooth issues, I had a lengthy chat yesterday with my dealer. There is a newer version than 513 which was supposed to have been released in February. Aparrantly, Mazda still aren't happy with it as an update which is why it's been delayed, although new cars are now arriving with the newer version installed. He also said that Mazda have instructed dealers not to replace any infotainment head modules, etc, that appear faulty until this is resolved... He's going to call me as soon as it's released.
I also asked him when the 2017 CX5 will be in the showrooms, that's also been delayed to June now.
