Gt9xx1024x600

For 1024x600, keep 0x804E = 0x00 unless physically rotated.

This is the most widespread use for the 'gt9xx1024x600' combination. Modern aftermarket head units for vehicles like Toyota, Honda, and Volkswagen use this setup for their 7-inch, 9-inch, or 10.1-inch displays. The GT9xx provides the multi-touch capability for navigation and media, while the 1024x600 screen offers clear visuals for maps, video, and vehicle information.
