Vehicle manufacturer's are now using CAN technology to drive the instrument cluster, this basically means the speedometer is ran like a computer and thus the KM series of units will not work.    To overcome this, we can reprogram the instrument cluster to run in miles and then fit a replacement dial face.    We also reset the odometer back into the correct total distance in miles as part of this conversion.

We are constantly in development with this type of speedometer, our current list can be found here.    An example is shown below, these are Nissan Cube instrument clusters, before and after conversion.
