Hi all. College student here with interest on remotely controlling a car stereo but am baffled on how to analyze. There are two parts to it, the head unit(that does that grunt work) and the faceplate that lets you control it. There's a connection between the two(about 14 pins i believe) and this is where I'm lost. I'm new to all of this. I feel as though if i can get past this hurdle, I can effectively work towards my goal.
Cheers.
