Anyone know if the 2014+ models support aptx over bluetooth?

I have a 2014 and I'm surprised this hasn't been answered yet!

I tried googling and came up short - from the sound quality it seems to be using AptX - but as I do not have a Bluetooth device that doesn't support AptX, I can't do an A-B comparison...

I've seen no reports that 2014-onward Mazda3s have AptX. Pretty sure you're just hearing the standard SBC codec maxing out its bit-rate (328 kbps).
