I'm replacing the speedometer (VDO) in our 86 740. How can I reset the mileage in the replacement to match the one in the car? (We have 400k miles -- all ours!!), and we want to continue. j corey
It's pretty tricky to take apart the odometers in the 700 series. I would connect a pulse generator to the input and let it run long enough to rack up the miles, it takes some electronics knowledge to throw something like that together though.
