I have a 2017 5.0 Lariat with Sync but without navigation. I actually prefer having access to Google Maps or Waze over the factory navigation. My problem is not a big deal but is irritating to me. When I first get in the truck and plug in my Android phone - S7 to the USB port, most of the time the navigation component does not start. If I unplug my phone and immediately plug it in again, it does load navigation. At first I thought it was the charge cord so I have tried multiple cords including the original charge cord and it acts the same way. I have tried starting Android Auto on my phone before plugging in the cable and that does not seem to help. Once it connects to either Google Maps or Waze, it works flawlessly. If I leave the phone plugged into the truck when I shut it off, the navigation starts immediately when I restart the truck.
Anyone else out there have the same problem? Any advice on how to get rid of this issue?

 

Just a shot in the dark. Have you tried opening the Android Auto app on your phone and going to settings/phone screen settings/Autolaunch and choosing your truck from the list of autolaunch devices?

 

My Samsung s6 would try to pair with my truck every time I plugged into the usb. My new MOTO z2 force won't. I unless I put it on blu-tooth . I figure it is either a setting in my phone or the new android version. I will work on it and report back. Definitely not the truck as it worked perfectly with my previous S6

 

After I plug my phone in to my truck via the USB cord, I then have to actually open my phone with the fingerprint sensor (or lock code, pattern, etc.) and as soon as I do that, it then connects to AA. It will not unless I do that.

 

Mine can take up to 30 seconds to launch. Occasionally waze/google maps will act up and i have to close all the running apps and it will be good after.

 

Try your settings, as mine connects and displays android auto on the sync screen as soon as it is plugged into my phone. S7 here...

 

My wife has an android and has the Car Play in her Mercedes. She has the same problem. I've been using Car Play in Ford pick-ups for several years with an iPhone and have never had a problem. My thought is its an Android issue. Additionally in general the iPhone interface just seems more useful and intuitive. Trying to convince her to make the switch.

 

there is a setting in Android Auto to automatically turn on bluetooth when launching AA. Maybe that will help

 

I have a 2017, and I have the exact same problem. I have to disconnect and reconnect the USB cable once, in order for Android Auto to connect.

 

Mine was giving me that problem when i was using an aftermarket cable i got from Amazon. I bought a new cable directly from Google and that seemed to solve the problem. Also, have your truck as a trusted device if you use a passcode/fingerprint to open your phone.
