I haven't had much luck using Android Autoplay, it seems from the interface on the stereo, to be something designed by a 12 year old in their first semester of programming class. I tell it to not load on my phone, which then causes it to ask how do I want to connect to the USB, and I say deny, and then it asks to install AA again, which I say not now, and the cycle will repeat, till I unplug it, plug in my iPod, and then plug it in, and then it gets upset that it is in charging only mode. I let that time out, turn on the phone, select deny to accessing things on my phone, which then causes the your phone is in charging only mode again. I can't do anything really with it on the split screen, and if I am wanting to use the on-board nav, it will take over, even if I tell it to go back to uconnect. As soon as I go back to split screen, it shows the uconnect nav for a bit, and then goes to AA.
I am guessing I am supposed to be doing all the stuff on the phone or doing some type of voice commands, but it just seems to be a bulky unwielding program. The Apple carplay has a much better interface.
