Review on different car audio systems
The SOUND FIRE NEXGeneration 9″ Inch QLED IPS Android head unit is a modern in-car infotainment system designed to replace factory-installed stereos with a feature-rich, Android-based alternative
Model Name (typical for this unit): Sony XAV-AX4000 or XAV-AX6000 (depending on version)
Screen Size: 7-inch Capacitive Touchscreen
When I first unboxed the unit, the screen felt solid and premium. The 6.8″ display is bright and clean — not flashy but professional. The touch response was smooth, and the buttons (where available) felt sturdy.
