Use mainmenu 3 of 3 and calibration.

Can someone put up the calibration tool again ?
Or the navcore with integrated calibration icon ?

THX holyhead.
On my Go630 it doesn't work for a penny !
I have the icon on the screen, when I tap it the screen becomes black (as stated in the included info)
But no crosses appear, certainly not the FIVE that should !
After 2 seconds the Tomtom starts up again as usual (tomtom sound, then the splash screen and the map).
So I worked it out the "old fashion way"
Copied the values which are programmed in the root of my GO630 (*),
(*) Start up the tomtom and after the sound , press start/stop again and hold till a black screen with all values appears.
These values are:
94 937 136 851
After that I created a cal.txt file with notepath, with the values:
937 240 851 136
and placed this cal.txt file in the root of the GO.
Watch the second value which changed from 94 to 240 !!!
Never thought it would differ that much
And ... everything works well !
