– enter the DAS ATEGO truck come and place manually and then it will work perfect
“Currently the speed limit is set to 100 km/h. I’m trying to set it to higher value (with DAS using modified EOL files). On the menu it tells me that I can, because there are higher values (105 km/h. 112 km/h, etc). But when I try to set the speed limit to higher than 100 km/h it doesn’t allow me to do it (can’t save the changes). When I try to set it below 100 km/h everything goes fine.”
