Direct-fit replacement for 2011 GMC Acadia

This professionally remanufactured OEM head unit carries part number 22921421 and is built as a direct replacement for the factory radio in the 2011 GMC Acadia. It provides AM FM reception, an integrated audio-video disc player and navigation-ready capability. The unit is cleaned, serviced and tested to 100 per cent working order before it ships.

OEM connectors and dealer activation required

The radio uses the original factory wiring harness and mounting points, so installation reuses the existing dashboard opening without adapter kits. Because the unit is navigation ready and tied to the vehicle data bus, a dealer turn-on is required to complete coding and enable full functionality. Verified interchange numbers include 638-03348 and GM 22739332, 20862548, 20876358.

Replaces a failed factory radio

This unit replaces a defective or missing factory radio only when the vehicle currently uses part number 22921421 or one of the listed compatible numbers. It will not work in vehicles that use a different part number, even if the plugs appear identical, because data streams and external amplifier configurations vary. Buyers who need a different part number or an aftermarket upgrade with modern smartphone integration should look elsewhere.

Questions about this item

Does the 22921421 head unit need a dealer turn-on to work?

Will this unit bolt straight into a 2011 GMC Acadia dash?

The 22921421 is built to the original factory dimensions for the 2011 GMC Acadia, so it fits the existing dash opening and uses the factory mounting points.

What is the step people miss when swapping in the 22921421?

Verifying the exact part number 22921421 or a compatible number such as 22739332 before ordering; units that look identical can have different data streams and will not code.
