• Installation Frame: Some users have noted that the unit may come with a black plastic frame internally.

Always check the fit before final installation.
• Heating Menu on Startup: If the heating menu appears automatically every time you start the car, check your car's original settings or the unit's system settings for options related to climate control integration or auto-display features that might be triggering this. Disabling such an option in either the car's system or the head unit's settings may resolve this.
