In my experience, using Android 9.0 on a Pixel phone, I don't get the Android auto features unless I plug in the USB cable. I only get the normal Bluetooth features (phone calls, etc.). The Android auto option doesn't pop up in my Niro's display until I plug in.I have an older phone and have to use Android Auto via a usb cord to my phone. I was told with newer a Android operating system (8.0 Oreo) you could use Android Auto fully wireless via Bluetooth. Can anyone confirm?
Not if both AA and CP updates make it work with compatible cars. I can't think of any function that requires bandwidth anyway other than a software or built in map update.
The implementation of wireless andriod auto uses wifi instead of bluetooth. So the head unit needs to have wifi capability to work. I don't know if the current Niro units do??
I did forget about screen draws. But since both Android and Apple claim to have full functionality through Bluetooth on compatible cars, I assume it is possible. Perhaps those models cache much of the possible screens. Only maps might be slower for the first draw.the bandwidth is that you are doing a screen projection from the phone onto your 7" (or 8") screen. Now there are ways to doing better compression for streaming screen updates but I don't think the block size and throughput on Bluetooth is enough to do screen image updates depending on what is being projected. Sure doing music is not a big deal, but I don't know if constant moving maps or any screen update intesive program will work. From Googles side it''s better to just require a plug rather than having screen issues.
