This has happened to me 3-4 times since I've owned the truck (about 8 months). I'll get in and start the truck, it will detect my phone, but Android Auto wont start. When I try to enable it in the Sync 4 settings, I get some kind of message about enabling App Projection, which it tries to do and then eventually times out. The only way to get it to start working right again is to kill the power to the truck and let it sit about 5 minutes. It hasn't happened many times, but it happened to me yesterday, so it's not something they've fixed in software it doesn't look like. I've had it happen on 2 different phones now.

Anyone else had this happen?

 

Yes! It's happened to me twice.
Make sure the phone wifi and bluetooth are on.
Delete all phones from your Sync 4 settings menu and start the process again.

 

I tried all of that plus everything else imaginable the first time it happened with no luck. For me at least, letting the truck sit a few minutes with the ignition completely off is the only way to fix it, but it does seem to fix it. I don't have to mess with any settings or anything, it just starts working again. Fortunately it hasn't happened very often.

 

Mine connects well most times. I still keep a USB cable plugged in the front console outlet. If I have an issue with connection I just plug it in. That seems to connect fine always. Issue has been hit and miss. I think it has as much to do with the phone as anything with the truck. If you do try to pair again mak sure you delete pairing in your phone, then restart phone. Don't turn Bluetooth and WiFi back on until you have also deleted phone from truck. That way you are assured one half isn't trying to connect to an old pairing on the other.

 

I had this very same thing happen this morning again for the 1st time in weeks and deleting phones from HU hasn't worked yet. I wonder if an Android Auto update messed something up.
Anyway, Wireless App Projection is off and greyed out. I am at work, so I'll have to play around with it when I can. I am trying the "let it sit" approach for now.

 

Went back out a few minutes later and it worked fine, just like you said.
Weird.
Oh, well. Maybe it will be good for a good while now.

 

yeah i can count the number of times it's happened on one hand. it's not one of those things that's gotten worse over time or anything. Just seems like it's likely to happen once every couple of months or so. Maybe once for every 200 or so times I start up the truck.

 

Only 4 times in 8 months? Lucky you! It happens to me once a week or more. lol

 

I have also had this problem. Not once a week, but often. I have been unable to find any solution. One of many issues I have been dealing with.

 

It's pretty infrequent for us. More often though once it connect the music is paused and I have to hit play for streaming from Spotify to resume instead of just starting from where it stopped last time.
