𝗜𝗺𝗽𝗼𝗿𝘁𝗮𝗻𝘁 𝗙𝗶𝘁𝗺𝗲𝗻𝘁 𝗡𝗼𝘁𝗲

This amplifier is intended for vehicles originally equipped with the compatible BMW Harman Kardon Top HiFi system.

It is not a direct replacement for:

• Standard BMW stereo systems  
• BMW HiFi systems with a different amplifier  
• Vehicles without Harman Kardon option S688A  
• Vehicles without the correct MOST fiber-optic connection  
• BMW X3, X4, X5 or X6 amplifiers with different part numbers  
• Aftermarket sound systems

Installing this amplifier alone will not convert a standard or HiFi-equipped vehicle to Harman Kardon. Such a conversion requires the correct speakers, wiring, fiber-optic network, vehicle coding and supporting equipment.

Before ordering, compare:

• Complete BMW part number  
• Electrical connectors  
• Fiber-optic connector  
• Mounting points and housing design  
• Vehicle production date  
• Factory audio option code  
• Original amplifier label

𝗩𝗜𝗡 𝗣𝗿𝗼𝗴𝗿𝗮𝗺𝗺𝗶𝗻𝗴 𝗦𝗲𝗿𝘃𝗶𝗰𝗲

The seller states that programming is included with this amplifier.

After ordering:

• Send the complete 17-digit VIN through eBay messaging  
• The seller will configure the amplifier for the supplied vehicle  
• The module will be bench-tested before shipment  
• Verify that the VIN and vehicle equipment information are correct before programming

Once programmed, the amplifier should be installed in the vehicle for which the VIN was supplied. Additional diagnostic fault clearing or vehicle-level initialization may occasionally be required after installation.

Confirm the exact scope of the programming service with the seller before purchasing.

𝗗𝗶𝗮𝗴𝗻𝗼𝘀𝘁𝗶𝗰 𝗡𝗼𝘁𝗲

Complete loss of audio does not automatically confirm a failed amplifier. Similar symptoms may result from:

• A disconnected or damaged MOST fiber-optic loop  
• Water intrusion near the amplifier  
• Corroded electrical connectors  
• Blown fuses or power-supply problems  
• Radio, iDrive or head-unit faults  
• Damaged speakers or wiring  
• Incorrect vehicle coding

Professional diagnosis is recommended before replacing the amplifier.

𝗖𝗼𝗻𝘃𝗲𝗿𝘁𝗶𝗯𝗹𝗲 𝗪𝗮𝘁𝗲𝗿-𝗟𝗲𝗮𝗸 𝗪𝗮𝗿𝗻𝗶𝗻𝗴

On F33 and F83 convertible models, inspect the trunk and amplifier compartment for moisture or evidence of water intrusion before installation.

Any roof, trunk-lid, drainage or weather-seal leak must be repaired before installing the replacement amplifier. Installing another amplifier without correcting the leak can damage the replacement unit.

𝗖𝗼𝗻𝗱𝗶𝘁𝗶𝗼𝗻

Seller-refurbished OEM component. The seller states that the amplifier is tested using professional equipment. Normal cosmetic wear, scratches or handling marks may remain from previous installation.

Review the listing photographs and confirm the part number and connector arrangement before purchasing.
