[Dead Eye]

If the face has been changed it would still be reasonably accurate - its entirely possible that they managed to get hold of a stock Fazer MPH face?

It may be worth keeping an eye on your odometer as well - this would be in KM instead of Miles as well as the Trip.

I can't say I've heard anything about holding the SELECT to change the setting. Most replace the clocks and attempt to find a set with a similar mileage. I think there was some mention of converting the pulse frequency but that wouldn't be especially helpful for any existing mileage...
