I have a dead cluster panel on my Prius Gen 3 , 2010 and I am going to order one from US. Before ordering I need to know 1. When we change speedometer from mile to kilometers (by pressing the button on dash) the instant consumption (MPG) and the other trip indicators on the cluster panel will be changed from M to Km or not. 2. It will have to br reprogrammed after installation? Appreciate any experiences.
