Aftermarket Infotainment x L/Certified Warranty

Hi,

I have a used IS 300 2024 bought directly from a Lexus dealer in April, so it carries the L/Certified warranty and two years of service. However, it has a horrible 8-inch screen since the original owner / dealer did not opt for the navigation package. I am thinking about replacing it with the Lexion screen after reading so many posts on clublexus, but I am not sure about:

- Would this mod void the L/Certified warranty?
- If so, which components? Or the whole car's warranty gets voided???
- Would the two years of service remain intact?
