i have a Lexus LS460 with the standard Kardon Harmon music system, the car has done 38,000km. Lexus will not warrant it as it has done 4 months over the warranty period. the amplifier makes a constant loud ticking noise whether it is switched on or of. Lexus said this is a common problem on this model and advised me to disconnect the amplifier plug which stopped the noise but also stpped any music, direction, or bluetooth phone. Cost of a new amplifier is over $2000.00
has anyone else had this problem and got an easy fix, I would believe it is only a small component in the amplifier which has failed.
