Porsche multifunction buttons module in steering wheel connect to steering control module by clock spring, LIN BUS as it's communication protocol.Different model&year Porsche use different LIN BUS protocol version and data bits definition.

The latest multifunction steering wheel and some other features are not compatible with old cars. So I decided to make an adapter to solve this problem.

Trusted by Porsche owner across the country.

This thing rocks! I got the adapter four days after ordering, and installed it in the new GT Sport wheel last night, then this morning I swapped out the wheels, and the multi-function buttons work just like factory. I’m totally satisfied and pleased to get this working after the dealer couldn’t manage to do so. Great product and service!


I order it Friday and receive it mondey from China to Europe. It is brilliant! Working perfectly on my 2011 Cayenne Turbo MF + heating Very easy to install if you know what are you doing . Took me around 30 min to install adapter into new steering wheel and 10 min to swap wheels.

This product does exactly what it claims to do. Brilliantly designed to fit snugly in a void within your steering wheel. Connection is very simple and the fitting instructions are easy to follow. The customer service, should you require it, is nothing short of outstanding. Anyone who buys this product can be reassured that they will have better ‘back up’ than most big companies. Fantastic product.

worth every penny!

if you are on this page, you probably already realized the pre "918-insinpired" porsche steering wheel looked like absolute crap compared to all these new ones coming out. There are tons of post on the porsche forums from members asking how to retrofit the newer style and boy, did GPS deliver! I have a 2014 Cayenne GTS with the MF/Non heating and I almost wanted to trade in my car so I could put my hands on the newer steering wheel, but now I don't need to! All I needed to get was this GPS adapter, new steering wheel and new airbag. I took it to a professional tuner shop who did this install under an hour and now the car is so perfect, everything works, MF, the buttons light up, the paddles all work and no warning light. if you are on the fence, read up a bit on it so you know what's involved and just get it! you will not regret it and GPS answered all my questions almost instantly and all the questions you will have getting this installed, he's probably seen it all. Now I don't envy the service loaners with the new steering wheel, I love my car so much more now, it's just perfect
