Avoid U-Turn?

Hi, does anyone know how to disable u-turn in any iGO (8, Primo 1.1/1.2/2) ? It sometimes asks me to do u-turns that are simply impossible. I have tried adding the following:

[route]
allow_uturn="0"

in sys.txt and system.ini in save folder, and nothing is changed. Any help is appreciated, thanks!

No need to change the system.ini.
Did you delete the "save" folder from the root of the program after adding it to your sys.txt?

Using this skin in iGO8, you can choose if you want to include u-turn option in your route planning or not:
Settings-> Route Planning-> Options-> U-turns (checkbox)

I tried deleting save folder and no dice
Will see how skin works...

Try a simulation when done. That skin keeps crashing on me when simulation is used but I have only tried this on the desktop version on igo8.

Is it possible to make an iGo Primo system offer u-turns?

Mine tries to re-route using some ridiculous routes, whereas a u-Turn would be so much easier.

I couldn't find it with the default skin nor with 2 otheres (diMka, Decent).
Maybe it will work with the entry for the sys.txt from post #1?

I agree. I wish I could get it to suggest U turns.

Does anyone know how?

I read about the skin SBERTAUD13 (which I believe is not updated anymore) in some version changes log: "Added "Avoid U-Turn in the settings of skin".
I think SBERTAUD13 only supports Primo 1.2. - Can be wrong however.
And the DECENT skin Primo 2.4) feature list says : "U-Turn visible if you select the advanced settings for vehicles".
