For the 2019 model year, Ridgeline RT, Sport and RTL trims gain a 1.0-amp USB Audio Interface in the center stack, and the USB port inside the center console becomes a 2.5-amp charging-only outlet.
The 2019 RTL and RTL-T trims add the one-touch power moonroof and the power sliding rear window already found on the RTL-E and Black Edition.
