In my first post, I said that in "Warnings" section of iGo, I do not have setting to enable speedcam alerts, there are many other warning types, but no speedcams. After research, I found a similar issue on iPhone (no speedcam warning setting to enable) and proper sys.txt file fixed the problem, but in my case this was again effort in vain, which can be because I have no access to the system files of iGo.
I will report on the "Choose navi path" tomorrow when I have access to the car.
