Central digital panel on the dash

I’m surprised it just the panel, usually you loose most if not all the accessories, the safest way to get it all back is have the dealer do a reflash, that way you get any software updates that maybe out there for your vehicle.

You might be headed back to the Dealer to have the computer reprogrammed. On many newer vehicles the computers must be powered up at all times, even during a battery replenishment or, as Ed92626 said, the computers will lose their memory. Hope that helps! Jim
