Well, I have after years of owning a Pioneer F900BT, I went and got myself a SPH DA120 today.
Wiring was straight forward and I reused my existing GPS antenna and mic, since they are the same anyway, and also the steering wheel controls have been retained.
Carplay works well, if limited to a handful of apps.
The only issue I have now is that my reversing camera doesnt work as expected and has stumped me.
I have connected it to the correct plug on the HU, I can get a picture when in "Camera View" mode.
If I turn on "Camera Mode" and "Back Camera Input" and then go into reverse, it autoswitches, but then i sometimes have to manually cancel the view by pressing the "X" in the top right corner, which then also switches the autoswitch off.
I'll give it another look over the next couple of days and see what I can find
