Please help, most of the time the stock alpine radio, factory antenna, and separate NAV screen located on center of dash instead of the three analog dials Will not power on/work. Periodically when I driving I’ll press the radio button and everything will work perfectly. When I turn the car off and then go to drive it again it’s back to being an operational until the next time it decides it wants to turn on. What could it be? I check the connections for the radio and the separate naff unit and all seem fine please any suggestions. Sidenote, I don’t know why they make it so difficult for fuse locations there’s nothing that I can find to show me what all the fuses are for. I’m thinking it’s a loose wire somewhere it can’t be a bad fuse because then it wouldn’t come on is that somehow wired into the ignition switch?
