Direct OEM Replacement Radio

This professionally remanufactured unit carries part number 23378511 and matches the original AM FM XM single CD mp3 receiver fitted to select 2015-2017 Buick, Chevrolet and GMC models. It is cleaned, serviced and verified for full function before dispatch. Buyers who need a different part number or a newer infotainment platform cannot use this radio.

Limited to Factory Feature Set

The receiver provides only the broadcast and disc playback capabilities designed for the original vehicle architecture. It does not add modern streaming, smartphone mirroring or digital radio standards beyond the listed AM FM XM and mp3 CD support. Vehicles that require dealer-level configuration for chimes, premium sound integration or steering-wheel controls may need additional programming after installation.

Swaps a Failed Factory Unit

This radio replaces an identical OEM part that has stopped working, restoring the original dashboard layout and vehicle data-bus communication without harness adapters. The jump is worth it when the existing unit shows the exact part number 23378511 and the owner wants to retain every factory feature exactly as delivered. If the current radio carries a different part number, this unit will likely not communicate with the vehicle systems.

Questions about this item

Which part number confirms this radio matches my vehicle?

The unit carries part number 23378511 and interchange 638-04673; only install it if your current radio shows one of these exact numbers.

What does the 100% working-order claim mean once the radio is installed?

Every function — AM, FM, XM, single CD and MP3 playback — operates as designed, though dealer configuration may still be needed for chimes, sound-system tuning or button mapping.

Does the unlocked radio plug straight into the factory wiring without extra adapters?

It uses the original factory connector, but data-stream differences between 2015-2017 Buick, Chevrolet and GMC models can prevent full feature operation without dealer programming.
