Will I need extra parts or coding?

Requirements depend on your original wheel, replacement wheel and vehicle equipment. Adding multifunction controls or heating can require a compatible steering column module, clock spring and PIWIS coding. Do not assume every upgrade is plug-and-play.

Review installation and coding guides.

Unsure about fit or an unavailable option?

Email info@gpsadapter.us with your Porsche model/year, the functions you want, and clear photos of your current and replacement wheels. We will help identify the correct configuration. If an option is unavailable, ask us before choosing a different configuration.

OEM compatibility and returns

GPS Adapter supports OEM equipment only. Non-OEM equipment is not supported, including aftermarket stereo configurations. Returns due to incompatibility with non-OEM equipment are subject to a $40 restocking fee.

Add multifunction controls and a functional drive-mode switch to a compatible newer OEM Porsche steering wheel.

Adapter-X V2 is designed for supported Porsche 991.1 and 981 applications. It synchronizes the steering-wheel Mode Switch with the vehicle's center-console drive-mode controls. If functional Mode Switch control is not required, compare STMV1 / STMV1-H.

Before ordering: review the compatibility guide and email clear photos of both steering wheels to info@gpsadapter.us. We will confirm the correct kit and required parts.

OEM equipment only. Compatibility with non-OEM components is not guaranteed. See the OEM vs. non-OEM guide.

Shipping: Free worldwide DHL/FedEx Express shipping is included. Local import duties may apply.

Porsche mode switch and multifunction steering wheel retrofit

Adapter-X V2 adds multifunction controls and a functional drive-mode switch when fitting a compatible newer Porsche steering wheel to an earlier vehicle. The system uses two modules: Adapter-A inside the steering wheel and Adapter-B at the center-console control module.

The modules synchronize the steering wheel mode switch with the center-console drive-mode controls through a private, low-power Bluetooth link. They connect automatically within approximately 3–4 seconds after startup. This connection is internal to the system and cannot be found or accessed from a mobile phone.

Installation notes

  • A 971-style replacement wheel requires the complete 95B-971-388-B internal wiring harness; the appropriate harness is included with 971-style kit configurations.
  • If the center-console buttons or mode switch stop responding, power-cycle Adapter-B by disconnecting and reconnecting its input connector.
