I've seen that Kia US has released an update to offer CarPlay and Android Auto to older Kia models. It seems that it doesn't have to go to the dealer as you just download an update onto a SD card.

I haven't seen anything from Kia Australia yet but I have sent an enquiry. Anyone know if it's available for Australian models?
I'm tempted to try it but I could brick the unit!
I'd be checking model numbers of the stereos involved
