Idea to keep standard stereo buttons
I havent been around for a while but i am thinking about rejoining the ranks and installing a new CarPC in my current car (2010 Ford Fiesta).
however if your not aware the stereo in the for fiesta is quite unique, it has a front panel full of buttons, a separate small screen and a hidden unit which controls everything.
For the last couple of years ive had a Chinese stereo installed which is based on Wince5 and is basically a Carpc that got terrible software and is drastically under specced. so i am thinking about keeping the 7" touch screen from this unit and stripping out all the electronics from the main unit and installing a new car PC. this is all great but it leaves me with 1 problem.
I have to keep the existing stereo button because to blank them off would just look silly, and if i keep them then i would like them to control the PC...
This is the issue i am stuck on at the moment. there are 30+ buttons on the panel, however there are only 14 pins on the plug. I am looking into using the RCJoyCon to accept the signals from the front panel and send them to the PC. so this leaves me with 2 questions:
1) will the RCjoyCon work in the way i am wanting
2) how can i work out which pin does what if there are only 14 pins then each button must share a pin with another button?
here is a picture of the front of the stereo
Thanks in advance and i'm sure there will be a few more questions to come later on
