Make Sure This Is Your Amp
Land Rover changed amplifiers when it changed infotainment systems. Cars with the
8-inch screen and buttons down both sides (2016 and older) and cars with the
10.2-inch wide touchscreen (2017 and newer) use different, non-interchangeable amps even in overlapping model years. The 380W, 825W and 1700W systems also each use a different amp. Run our
Amp Finder or match the label on your old amp before ordering.
