Hey guys, long story short, I bought a second hand head unit for my car as a spare so I can mod it (Id rather not attempt it on mine) but the problem is, I dont have the pin code for it. It uses a 4 digit pin code, and only numbers 1 to 6 are used (so only 360 combinations). My plan was to just hook it up and just smash through the combinations until I find the right one but after for failed attempts, the head unit locks me out for an hour. I opened the head unit up and its got an m30622mca-8m9fp chip in it. I googled for the datasheet, and I noticed its got a reset pin on it. Im reading about how to reset it, but I really dont understand what its saying. Is it saying that I need to connect the reset pin to 0.2V for a certain amount of time and its done? would resetting it mean it resets the the 1 hour lock?
