I have a Disco 2 2004. Recently the odometer jumped by 70K when battery was replaced.

I would try disconnecting the negative terminal of the battery.

is there a setting to change the reading between miles and kilometers?

Thanks Mark. That is more than likely it. It did not even cross my mind. That makes sense when my temps for heater and AC and outside temp are now in Celsius. I tried looking in the manual to switch back to Fahrenheit but could locate it in manual. Would you know how to do this?

sorry I meant Mike.

You are welcome. Can you click my answer as "helpful" please. The manual should have instructions for switching to US Imperial from Metric. Unfortunately, I am not familiar with your make and model of vehicle.

Change it back by holding the odometer button until it changes.
