This digital speedometer is a game changer for the BMW E65 7 Series, a car that is notoriously known for water leaks and overheating has no quick access or visual temperature guage which to me is unbelievable. I bought this unit as I could see from the images a temperature guage was visual in the advertising and I took the chance and purchased this item and it’s paid off. Not only does this unit show coolant temp, but oil temp, battery voltage and several other stats. You have several displays to choose from, and several different car displays to choose also, but this has changed the visual presence of my dash, brilliant.
