Problem is mainly when you're trying to stream HD audio with AAC codec.
On Google Pixel 5 / Android 11, this is easily fixed without spooky developer stuff:
1.) Long-Press your Bluetooth icon while connected to your truck.
2.) Click the little gear icon beside the Uconnect device that you're currently connected to, which brings up the Bluetooth settings for your truck's connection.
3.) First setting is "HD Audio: AAC". Toggle this to "Off" / make it gray.
Immediately you should see the lag diminish to something that's basically inconsequential.
This setting should persist in this device for as long as it remembers that particular Bluetooth device. Survives disconnect, reboot etc.
