I have an Android phone. I have a USB with my favorite 500 songs (ha!) plugged in to USB Port 2. I have a short cable plugged in to USB 1 - I hook my phone to it when I want to use Android Auto for Navigation.
When using AA Navigation I have to disconnect my Bluetooth phone - cannot use AA and phone at same time. I think this is a limitation because of my low-level truck (Big Horn, not Laramie). But 8.4" screen shows AA Nav very well, I just can't use my phone.
If I want to disconnect AA, then my phone will work again.
Music still plays just fine (I like to use the shuffle feature, and I love the buttons on the back of the steering wheel to skip ahead a track if I don't feel like listening to what comes up, and to adjust volume for how I originally recorded the tunes).
