Infotainment system — while driving suddenly there is a cracking/ shrieking startling noise and infotainment system gs off shutting down ( network communication lost sign comes on) and the screen gs blank. No camera works. Radio and all electronic display gs off for a couple of minutes. Slowly, it begins to come back to life by itself in a couple of minutes. This happens randomly on and off. In last 4 weeks, it happened at least 15 times while driving. Honda dealership has my car for three days without a diagnosis or correction.
