Just had shop install new battery in '13 Toyota Corolla; runs fine, but when I turn on the headlights, the audio LED screen goes blank. Adjusted LED settings to brightest, but made no difference. Dealership service desk has no clue. Bring it in, they said....again! Maybe a setting problem, fuse problem, who knows? But definitely was not doing this when I took it to the shop for a SIMPLE repair (new battery). Anyone else have a clue or suggestion? Appreciate any input. Thanks.
Frustrated in Florida. Had dealership shop replace dead/dying battery. Now turning headlights on makes audio LED screen go blank. What the heck?
