A54 Tachometer LCD blank..?

Chris Likins


I just installed a new tachometer on my A54. I plugged it in expecting it to work but menu is not appearing on the LCD screen. The LCD momentarily flashes “volvo penta” and then goes blank. Before the main menu would appear automatically after engine start...? Seems like I’m missing something super simple here.... 

Any Volvo EVC experts out there?
