If you have a 997.1, you will need to upgrade the steering column module to 997.2 (997.613.289.00/997.613.289.01), without steering heating support. Heating is currently not available for 997.1. This is details about 997.1 upgrade to new steering wheel https://gpsadapter.us/blogs/installation-guide/997-1-upgrade-to-997-2-steering-wheel-control-module-coding-guide

We do not guarantee adapter will work with aftermarket stereos. There is a possibility, though if you already have it working with a stock steering wheel that it may still work without having to do anything. But if it doesn’t, you will need CANBUS decoder for example, pioneer, or Alpine. https://mrcanbus.com/products/paser-unican-plus-steering-wheel-control-canbus-interface

981 Sports Steering Wheel Upgrade to 991.2

I decided to upgrade my 981 heated MF PDK steering wheel to a 991.2/718 version with similar functions. As such a STMV1-H adapter was needed. After a bit of intense installation guide studying, the preparations of installing the adapter in the new wheel was completed (with only one re-work). The placement of the adapter in the new wheel had to be re-done, so if any comments to the installation guide maybe a sentence on the need to push it inwards to make sure the airbag module fits.
The end result was excellent. All functions working as required.
A final note: Torque settings are not listed in the installation guide either. Maybe something to include? The backing plate as well as the fixation bolt need specific settings and most you tubers miss this out all together. The backing plate torque is important for the horn to work (just to name one key benefit).
Apart from that, a top product.

Upgraded Porsche 981 Steering Wheel to a 718 MF Steering Wheel Wheel

Very quick delivery - I ordered the GPS Adapter STMV1 on the 11/07/2025 and received on the 17/07/2025. Installed the adapter and all steering wheel functions working without any problems - Didn't need to buy a code and code it in. I went from a 997.2 type steering wheel without MF but my car had 'Sport Chrono' package so guessing it must be already be coded for MF.

The customer service was outstanding.

My car is a 997.1 Carrera 4.
I installed a 991 steering wheel, and I couldn't be happier!
The seller was incredibly kind, patient, and knowledgeable—answering all of my questions thoroughly and honestly, which gave me complete peace of mind throughout the purchasing process.
What impressed me even more was the amazing support after the sale. The response time was lightning-fast, and the guidance I received during the installation was spot-on.
Everything went smoothly from start to finish thanks to their professionalism and genuine care.
This level of service is rare to find these days.
Highly recommended — truly top-notch in every way!

All good except that you sent me the same switch for the heated wheel that I already had… So everything works except the heating but that’s not a big deal.
