Steering wheel buttons for aftermarket android head unit
 

I have recently installed an android head unit on my 97 boxster (manual).

I would love to have some control buttons on the steering wheel. My stock wheel is the 4 spoke kind. Is there any other Porsche or aftermarket steering wheel (with buttons) that will fit in this car. Has anyone done anything similar. I looked but couldn't find anything on the forum.

Thanks in advance.
