1 Factory Radio 2129001919 Receiver AM FM Six-Disc CD Heated Seat Control

2013 Mercedes-Benz CLS-Class Radio CD Player

This professionally remanufactured receiver replaces the factory head unit in a 2013 Mercedes-Benz CLS-Class. It integrates AM/FM radio, a six-disc CD changer and heated seat controls in a single module. The unit is sold as a direct replacement for part number 2129001919 and carries interchange part number 638-59500. Buyers who need a unit for a different model year or vehicle platform cannot use this part.

Factory coding and amplifier compatibility

Dealer programming may be required before the receiver functions in the vehicle. Data-stream differences between otherwise similar units can prevent coding, and vehicles equipped with external amplifiers may not allow interchange. The supplier lists compatible part numbers 2129000917, 2129001316, 2129001719, 2129005818 and 2129009016 as additional references. Installers without access to dealer-level diagnostic tools should verify coding capability beforehand.

Exact part-number match requirement

The single specification that decides fitment is an exact match to part number 2129001919 or one of the listed compatible numbers currently installed in the car. Visual similarity and identical connectors do not guarantee compatibility because data protocols differ. Buyers who cannot confirm the existing part number must obtain it from the vehicle VIN before ordering.
