I can confirm that truck restrictions do work.
He calculates other routes to avoid tunnels, and when you don't take the exit, the program shows a warning.

I did the test yesterday at the same route and with a route planned you are guided to another road around the tunnel.
But if you don't have a route planned, you do not get any warnings at all.

I will post screenshots later, as I'm not home right now.

Never had tried World or Basar or Sygic.
I'm no expert....in installing, have to read a lott to get it working...

Never looked at Sygic ? Do you think this is better for Truck ?
If so, I'm gonna try, cause that's the only thing I need.
