I have a G13 for a 2016 Toyota 4Runner Limited with JBL. I do not get notification sounds for text messages. I have tried to turn on the notifications for ZLink in the settings, but when I exit the screen, the setting toggles off again. I have tried downloding the firmware updates listed above, but I get the same result. Is there a firmware and/or MCU update that is specific to the unit for my 4Runner?

Thank you.

I am having the same problem with my new dasaita g13 unit for my 2017 toyota tundra 1794 model.
Apple Caraplay text notification tones don't work here either. Starting to really regret buying this unit

Hi there,
The CarPlay text tone issue is usually a quick settings fix, not a problem with the unit itself.
- Enable "Announce Messages with Siri" in CarPlay settings.
- Turn off Do Not Disturb/Driving mode.
- Turn up volume when Siri reads messages (separate alert volume).
- Restart the phone and head unit.
Let us know if the problem continues.
