2009 Lincoln MKS factory radio replacement

This remanufactured head unit carries part number 8A5T-19C156-AK and matches the interchange reference 638-02647. It is built as a direct replacement for the original equipment in the 2009 Lincoln MKS and requires no unlock code to operate. Buyers who need a different part number or whose vehicle uses an external amplifier will find this unit incompatible.

AM FM 6-Disc CD navigation capabilities

The receiver provides AM and FM tuner functions together with a six-disc CD changer and integrated navigation features. It handles standard radio playback and disc-based media while supplying navigation data through the factory interface. The unit does not support modern streaming services, smartphone mirroring or additional digital audio formats beyond the original specification.

Plug-compatible fitment constraint

Installation depends on an exact part-number match; the data stream must align with the vehicle's existing wiring and module coding. Even connectors that appear identical can carry different communication protocols, preventing the unit from coding correctly. Verifying the part number against the vehicle's VIN before purchase is essential to avoid fitment issues.

Questions about this item

Will the 8A5T-19C156-AK unit plug into the existing wiring harness of my 2009 Lincoln MKS without adapters?

The unit is a direct replacement for part number 8A5T-19C156-AK and compatible numbers 8A5T-18K931-BH and 8A5T-18K931-BJ; matching the part number ensures the factory connectors fit.

How can I confirm the navigation and 6-disc CD functions are operating correctly after installation?

Insert a known-good CD to verify the changer loads and plays all six discs, then enter a destination to confirm the navigation system calculates a route and provides guidance.

Does the box include a GPS antenna or any external amplifier modules required for the navigation and audio features?

The listing covers the head unit only; any GPS antenna, external amplifier or vehicle-specific wiring adapters must be sourced separately.
