there was an iOS update that included CarPlay fixes. I have an iPhone XS and updated the iOS. Since then I have noticed a few things:

no random disconnects from CarPlay where I have to unplug and plug back in The phone

when stopping the car and turning it off with the iPhone connected via wired usb, it retains the connection when i start back up so no more unplugging and plugging back in.

when taking a call or doing anything else on the phone that would cause the infotainment to switch sources or whatnot, when the task is completed it goes immediately back to what it was doing beforehand. So no longer need to select the last source or flip back and forth to get it to come back.

seems like apple fixed the main issues people were having. I recommend updating your iOS regardless of device. I think this was for the X, XS, and XR mainly though.

so it looks like disconnects were related to the iphones firmware and not as much Acura at least for the last gen phone models

yup so maybe That will put out some of the fire directed at Acura for these particular issues 😆

have you replaced the usb cable and are you using an apple approved cable? I had bad disconnect issues which I narrowed down to the cable. But still had some after replacing it. Since the iOS update though it’s been solid
