When driving from Brooklyn to Manhattan recently I had the Nav preferences set to Avoid Tolls Roads and still the computer directed me to the midtown tunnel which is a TOLL tunnel. Given there are plenty of other non-toll options to get to Manhattan (Brooklyn bridge, Williamsburg bridge, Manhattan Bridge, Queensboro bridge) I am confused as to why the system did this. I tried changing the preferences to fast route, short route, with highways, avoid highways, etc. (all while retaining no-tolls), but the system wouldn't change its mind. Does anyone know if this is a function of the Nav computer (and operating system) or the Nav data disk itself? I'm running ver 29 and the latest nav disk.
