Changing from Mph to Kph speedometer needle goes out
Hi everyone thanks for letting me join your forum 
I have a 2004 sl500, My car is setup like this.
Odometer is in miles, my speedometer indicator says mph also, However my Speedometer needle reads in Kph.
My problem is when that when i change the speedo/odmeter from miles to Kmph, the speedometer needle jumps up about 40% out of whack.
For example I will be doing 50kph and whilst driving I will change the display from miles to km via menu and the speedometer needle will jump up to about 80kph even though i am still doing the same speed.
I took the car to a star diagnostic specialist and he could not work out what was going on.
Any help would be appreciated.
Regards

Hi,
living in a metric world, my speedo is usually set at kmh. When we hopped over to England, I swapped to mph. The speed numbers being printed, ‘hardware’, that results in a speedometer with a max speed of 260 mph. Nice! 😋
Question if I may: what happens in a car in mph country, when switching over to kmh?
