I hope that's the case. I've been doing some research and have seen some complaints regarding the current system. It's pretty much the only complaint that I've seen. I've been hearing the rumors regarding the possible update and have been crossing my fingers and waiting it out. Otherwise, I would just get a 2020.
Also, the US 2021 Mazda 6 was announced this morning with wireless Apple CarPlay on the "old" infotainment system.Mazda Canada is engaging people on the topic on Twitter. Seems legit. I see the info is also in their official media release pdf doc. too. This seems to be real.
Apple requires "authentication chips" for wired CarPlay which is why the USB hub must be upgraded in addition to the software to support wired CarPlay. I would imagine wireless CarPlay also requires something similar.Seeing as the Mazda AIO tweaks allow you to enable wireless Android Auto (on the Gen2 cars), I would think that the hardware is there, it's just a matter of software programming.
