What you are referring to is standard bluetooth integration, it has nothing to do with Android Auto.It is a bluetooth launch of Android Auto on my phone through the Lexus (which includes Pandora and Waze), that's what I was saying. As I mentioned, it does not control the 12" screen with maps or takeover the whole head unit, however, because Android Auto integrates Pandora, phone calls and texts, my screen will show what song Pandora is playing, phone calls and texts, which is standard on the Lexus GS for those functions. I don't expect you to know that about a vehicle you don't own.
Regarding the 2 wires to the single data port, I'm not trying to run 2 phones at once into the data source. Only trying to make it simpler to plug the phone in since my wife and I have different phones/plugs. And even if we were both were in the vehicle, only 1 of us would/could hook into the data port.
Let's not get too overly sensitive.
I understood you weren't trying to use 2 phones at the same time, you just want it easier to switch between devices without having to swap cables. Unfortunately since iOS and Android devices use different cables, and for full Android Auto / Carplay to work you need it to be connected by USB cable, the only option is to swap cables in the single port when you want to use the other device.
I sincerely hope my responses didn't give you the impression I was testy or annoyed, I wasn't. I was just trying to make sure when we talk about Andoid Auto/Carplay and standard bluetooth integration that you understood the differences. As well as that wireless integrations of Android Auto/Carplay that don't require a USB cable are still in their infancy and won't ever be rolled out via a software update as most vehicles today don't have the hardware necessary to support that. Meaning if your vehicle (like the MDX) supports USB for AA/CP, then you will always have to use the USB cable. Conversely, if you don't need full AA/CP integration to your point you can use the standard bluetooth link with your device (which doesn't include maps/navigation/turn by turn directions in the head unit or MID).
