Hello to all. Does anyone have experience with replacing a Bafang DP C18 CAN display. The motor is a Bafang M500 on the Crussis e-bike. Water got into the display and as a result the glass is fogged. I already have a new display, but when I connect it, all the data is lost. I would like to somehow make a backup on the old one and restore on the new display. Please advise.
