Installation may require Jaguar Land Rover diagnostic software such as SDD or Pathfinder to:
โข Configure the amplifier to the vehicle ย
โข Load the correct calibration ย
โข Update the Car Configuration File ย
โข Assign the correct speaker channels ย
โข Clear communication or MOST-network faults
An amplifier removed from a different model may power on and produce sound while still having incorrect speaker-channel assignments or missing surround functions. Professional programming is strongly recommended.
This module should not be assumed to provide a plug-and-play upgrade from a base or lower-output audio system. Such a conversion may also require additional speakers, wiring, configuration changes and compatible infotainment hardware.
