Das-Kit display

[Uncle Willy]

Have a Das Kit L6+ and over a thirty mile ride odometer is off by two miles , compared to iPhone and Garmin watch .
Can this be adjusted in any way or are they just that inaccurate ?

The Das Kit settings on my Magnum Metro+ display (I think it's a C7) can be adjusted for tire diameter, perhaps it's set wrong? I have noticed mine is off some but only about half a mile over my 35 mile commute and I have double checked the tire diameter a few times.

will check and see if it can be set
