Not sure if this has been posted or not (didn't read the entire thread, sorry). I just did the following to recover mine after it stopped working a few weeks in:
- Forgot the bluetooth connection on my iphone
- Forgot the wifi connection on my iphone
- Deleted the phone from the 'connections' section of the truck
- Deleted the trusted device from the truck
- Held down the hangup button for 20 seconds and let the truck reboot
- Went to the "CarPlay" section of the iphone settings
- Went to the connections section in the truck, then to phones, add phone
- When the truck showed up as an available vehicle in the CarPlay section of the iphone settings, I clicked it
That took me through the standard pairing stuff (codes, click pair on both screens, etc) and then CarPlay started working again. I've drive the truck (off / on) 5 times or so today after doing this and all seems to be well. Fingers crossed.
