display screen error after battery replacement

[jasweett]

Recently replaced car battery, after replacement my display doesn't show rear view camera? When I purchased 2010 ls460 it had 135k mi and dealer stated nav not working? for the most part get error on nav screen but audio and rear camera and climate displayed on screen with no issues? Now nothing displays after battery replacement. 2 questions can it be rebooted? Is there a aftermarket replacement that will read factory nav or is the nav hard drive system corrupted?
