Hey I recently installed my f90-bt with your guys help, for a week it has been working amazing other then a little hiss sound from the speakers when nothing is playing..Today while driving I stopped at a light, when I stopped at a light and my car turned off by itself, and all the electronics reset including my head unit. It just turned on and off. Before I got home my car turned off a couple more times, but its only when I stop, if I am moving it wouldnt turn off. After making it home i went to go to bed because i have work in the morning and i closed my door and noticed the head unit would not turn off. I had no choice and for now I pulled it out and pulled the power from the back, does anyone know what could be causing this problem?
