The Blue Plug may require a tiny trim/chip of plastic for a secure seat. Do not force it—if it doesn't click, check for alignment.

Troubleshooting (FAQ)
🔇 No sound after installation?
Switch your factory radio source to AUX. If you have a factory amp, ensure the Amp Remote wire is connected.
❄️ AC Controls not showing on screen?
Go to Settings > Factory (3368) > Car Model and select "Acura TL". Ensure the CANBUS box is blinking (indicating data flow).
