I live in Illinois near Chicago, so I frequently have to travel on our toll roads. I also have an i-Pass transponder that allows me to travel in the i-pass open road lanes and skip the lanes with the toll booths. My navigation system is aware of the i-pass system and shows the simulated overhead signs reading "i-pass" above some lanes and "toll booth" above others. My question is: is there any way to let my nav system know that I have an i-pass? I've looked in all of the settings and can't find anything. It gets annoying because route guidance always directs me to use the right lanes with the toll booths. When I stay in the left lanes to use the open road i-pass lanes, it must be far enough away from the toll booth lanes that it causes my system to recalculate as if I left the route completely. Any suggestions?
