In this category, you will find adapters for maintaining steering wheel controls on Hummer vehicles when replacing the original radio with a new aftermarket model. These adapters ensure full compatibility between the multifunction steering wheel and the new head unit, so you can continue to conveniently control the volume, skip tracks, or answer calls directly from the steering wheel. We offer adapters for various Hummer models. Choose the right adapter for your specific car type and car radio model (e.g., Pioneer, Kenwood, Alpine, etc.) so that you can continue to conveniently control the volume, skip tracks, or answer calls directly from the steering wheel even after replacing the car radio.
