Ok, I thought the lines that appear on the screen would go away, but even after 8000 miles, it's there . It's not there all the time but it's noticeable at night time.
Someone said b4 that it's cause due to the refresh rate and it should go away.
Should I bring it back to the dealer?
Would this be covered?

Everytime I bring the car back when there is a problem they are saying it's not covered cause aftermarket alarm may have caused it.

Can this be true?
SHould I bring it so they can replace my navi?

Thanks
