For the first issue:
Ensure that your cellphone is connected to Tesla’s Bluetooth.

Use the CarPlay/Android Auto app to play audio instead of Tesla’s native app.

If both Tesla’s native app and CarPlay/Android Auto are playing audio simultaneously, it may result in the sound not working properly. To resolve this, refer to step 4.

In Tesla’s Bluetooth settings, select “Bluetooth” as the audio output.

For the second issue:
1. Check if you have checked the “Remain connected in Drive” box when Tesla connects to T2C’s WiFi. If you have not checked it, please do so.

2. If you have already checked the box and the issue persists, try disconnecting the Tesla from the T2C’s WiFi network. Then, reconnect to the WiFi network and make sure to check the “Remain connected in Drive” box.

By checking this box, it ensures that the CarPlay or Android Auto connection remains active even when you are in reverse or driving. This should help resolve any disconnection issues you are experiencing.

Android phone calls not going through car Bluetooth, only speakerphone
Putting car in reverse and then back into drive minimizes the web browser. Not sure if this is how it’s supposed to work.
