Why is my infotainment screen flickering?
Occasionally my infotainment screen on my 2014 Corvette Stingray will flicker. The only way to correct it is by blowing the horn. Why causes this and how do I fix it?

An educated guess would be that you have a weak ground. By blowing the horn, which draws a lot of power, will force more amps through the ground causing a better connection for a little while. In need of a wire diagram to find where the horn ground and the infotainment center ground are located together or any other shared wires, connectors and grounds.
