Hi Rangenistas,

switched to MK4 (with V32 firmware ) which fomer worked in a BMW X3. The X3 has smaller wheels, I have 19" with 255er.
On other nav systems you have to change the settings for the wheels rolling circumference.
Maybe thats why my system shows/tells not very exact the dimensions, e.g. I have to turn left, the road is vis a vis but system shows another 10 or 20meters.(bad, when there is a second road in that distance)

Do I have and where do I have to change the settings, which point in the hidden menue (is it gyro ?) and what digits for the 255er wheels? size in cm?

Thanks in advance XJC, RRV8, Series1 86 and 107% of real pleasure
