Issue with above solution is as follows:

- when I change time sync in sys.txt file to 0
- deactivate autosync in igo options manually, set time zone manually and set winter/summer time manually too

Problem:
- when I try to calculate route, the time of arriving is get from system time - not manually set by me time

How to change this in IGO to calculate arrival time from date/time set manually by me, no from system time ?
