I have a aftermarket PANASONIC (not the best) stereo and i noticed that every time i turn on my car that it wont automatically turn on i have to push the power button for it to turn on and lets say i save my favorite radio stations and adjust the clock on there it saves but when i turn off the car and turn it back on i have to do the same thing, push the power button for it to turn on and my stations are gone and th time. So anyone ever had this problem? or know how to fix it? it does this with every stereo ive installed before
