This is yet another example of a car company unable to realize that they just don't make good car infotainment dashboards. This will just lead to further fragmentation of the Android ecosystem.
Which sounds more like they got a better deal from Apple.
I don’t necessarily blame apple for this, but they clearly didn’t put strict enough requirements on the hardware that runs CarPlay.
I never bother with Carplay for less than a 1 hour trip.
As you say, it is probably a problem with some hardware.
