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?
Ist dies eine gute Frage?

I'd load test the battery and ensure it's cranking amps are up to snuf
As of March 2022, General Motors (GM) has not recalled the 2014 Chevrolet Corvette Stingray's infotainment system. However, some owners have reported issues with the infotainment display, including flickering and going blank. GM has provided a software update and a TSB for 2014 models with these issues, which may resolve the problem. Some dealers have also released replacement screens for the flickering issue.
Pretty much update the software and hope it resolves the issue
If not replacing the screen seems to be in order.
I'd love to get my hands on and investigate the true cause of the issue to see if a custom pcb mod with additional capistors could stabilize the screens output. Much loke the corvette repair community has sloved the c5 ecbm abs light issue with an upgraded solder in relay on the EBCM module.
With the price of parts and service on corvettes being high, it's actually economical to develop custom solutions for various electrical issues.
Its important to know pretty much all corvettes push their electrical systems and battires to the max with no features left off the table in design and development which often comes at the cost of reliability.
Does a high prefromnce AGM battery like Optima odyssey or x2 power help prevent these issues?
I know high end agm battires have lessened the various electrical issues on my dad's c5
The corvette owners forms & Facebook groups are always a good place to dig for solutions for every common or uncommon issue with all models.

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.
