Since we need to need to open both the WiFi and Bluetooth on your phone&the head unit to enable wireless CarPlay ,please check if the WiFi ant has been connect properly.
If not luck,please try to update the system and we've sent to your email
There are a couple places on my commute where carplay begins to become unresponsive. This sometimes results in the audio going in and out. But sometimes this can result in a complete disconnect (the zlink screen comes up) and carplay will reconenect 90 seconds later. It is very consistent. So some kind of interference is happening. Any tips? I updated to the latest firmware, but that does not seem to have helped.
