2009 Mercedes-Benz Gl-Class Camera Amplifier Part Number A 211 870 51 89 Silver Wired Mounted 100K Miles

This is a Mercedes-Benz amplifier module manufactured by Harman/Becker, specifically identified as M/N 9010 and labeled with the OEM number A 211 870 51 89. The unit features a rectangular metallic-silver housing with four mounting holes, and a factory label displaying both Mercedes-Benz and Harman/Becker branding. The label confirms its use as an amplifier, with a 12V power rating and a Q02 code. The black connector is present on one side, and all original mounting points are intact. The metal finish shows minor surface wear consistent with normal use, but there are no signs of damage or corrosion.
